Abstract: A protective device for an aciculate object includes a body, a capture, and a protective cap. The body is a geometric shape with two ends. The body has a longest side of length L1. The body is resistant to deformation along an axis parallel to the longest side of the body. The capture is formed into the body at one end. The protective device is pushed over a pointy or pointed end of the aciculate object positively engaging the capture of the protective device. The capture retains the aciculate object and resists movement of the aciculate object coaxially off the aciculate object and in a direction normal to an axis parallel to the longest side of the body. The protective cap is mounted to the end of the body opposite the capture. The protective cap has a diameter L2, such that L2 is less than L1. The protective cap is resistant to penetration from the pointy or pointed of the aciculate object.

Abstract: A fastener having an enlarged head and a threaded portion with an interior cavity. A plug mounted in the cavity configured similarly thereto having an enlarged head generally the same outer diameter as the enlarged end of the fastener and abutting against the same closing off the opening leading into the cavity. The plug is releasably locked in the cavity and released by magnetic action when the releasable lock is released.

Abstract: A crime preventing screw having a recessed portion for receiving the end of a driving tool. The recessed portion is formed with a recessed engagement portion at a partial lace of an inner wall. An embedding material for embedding in the recessed portion of the screw has a shape and size such that it can be buckled in and can be embedded in the recessed portion.

Abstract: The invention relates to a protecting cap for the head of a screw that is screwed into a constructional part. A body (2:7) is arranged between the protecting cap (1) and the screw head (3) and produces a positive and a non-positive fit therebetween. The protecting cap protects the screw head from mechanical damage, soiling or corrosion.

Abstract: A method and apparatus for restricting rotation of a threaded fastener, the apparatus including a bracket member having a securing segment and an extending segment that are integrally linked wherein the securing segment forms a recess and the extending segment forms at least one restraining surface wherein a bonding material that solidifies and remains flexible upon curing is provided within the recess and, with the threaded fastener received within an aperture, the bracket member is positionable such that one end of the threaded member is receivable within the recess and within the bonding material prior to curing and the restraining surface contacts a surface of a receiving member to restrict motion of the bracket member about the aperture.

Abstract: A captive fastener device is utilized to hold two members together. The device is comprised of a housing which may be securely attached to the first member. Within the housing is a spring which biases a bottom of a first lip of a cup washer. The top of the first lip contacts the top of the housing when the fastener is not engaged. The fastener has a ledge at the bottom of the fastener head which rests on a top surface of a second lip of the cup washer. The bottom surface of the second lip contacts the first member when the fastener has fully engaged the second member to secure the first and second members together. The first lip of the cup washer has a greater diameter than the second lip. The first lip also has a greater diameter than the fastener. When the fastener is not engaged, a top surface of the first lip engages a bottom surface of the top of the housing.

Abstract: A two piece retainer assembly is used for positive retention of an associated vehicular floor mat to the vehicle's floor surface. The retainer assembly works in conjunction with a hook-like fastener permanently mounted to the vehicle's floor surface. The two piece retainer assembly comprises (a) an annular collar for positioning in a hole in the floor mat from an underside, and (b) a locking cover coupler for positioning in the hole of the floor mat from an upper side. The annular collar and locking cover coupler are forced together to trap the floor mat. The annular collar has a vertical upwardly extending wall forming an opening and a horizontally radially extending flange connected to the vertical wall. The locking cover coupler has a base plate with a vertical downwardly extending wall forming an opening and dimensioned to receive the vertical upwardly extending wall of the annular collar in frictional engagement. At least two vertically extending latching tabs extend from the base plate.

Abstract: A locking device for securing outboard motors and stern drives mounted on a plurality of exposed studs on the stern of a boat, and construction equipment on a plurality of exposed studs inset in concrete or other media. The invention consists of a stainless steel lock nut, a lock body, and a lock assembly having a lock catch.

Abstract: A fastening device (10) including a fastener (20) and a recess insert (12) retained within the head (21) of the fastener (20). The fastener has a head (21) at one end and a threaded shaft (25) at the opposing end. The fastener head (21) has an engagement recess (22) and a concentric counter-bored section (28). The counter-bored section (28) has a greater diameter than the diameter of the engagement recess (22) and extends into the fastener head (21) less than the depth of the engagement recess. The counter-bored section includes an insert retainer (24). The recess insert (12) comprises a different material than the fastener (20). The insert (12) has a fastener retainer (18) and is adapted to fit within the fastener head (21) counter-bored section (28). The insert (12) has a head (13) with an aperture (14) for permitting access to the fastener engagement recess (22) therethrough.

Abstract: The present invention entails an enclosure that encompasses and protects a lug and lug nut extending from a wheel hub. Structurally, the enclosure comprises an end wall, a surrounding side, a snap on end cap, and a lug opening or port formed in the end wall. When installed, the lug extends through the lug opening and supports the enclosure while the end wall lies exteriorly of the lug nut and the surrounding side is spaced from the lug nut but generally encompasses and surrounds the lug nut and the lug. Prior to enclosing the enclosure by snapping on the end cap, the enclosure is filled at least partially with a grease or lubricant.

Abstract: A fastening element for attaching plate-shaped boards, and including a large-surface clamping member (2;22) with a hollow-stem (3;23) projecting from opening in the clamping member (2,22) with a hollow stem (3;23) projecting from and having a bore (5;25) opening in the clamping member (2;22) for receiving an expansion member (14) for an anchoring member (4;14); and a plug-shaped member (9;29) attached to the clamping member (2;22) with a strap (8;28) for closing the bore and having a plug-in section (11) with a sealing surface (12;32) sealing by cooperating with the bore wall and is force-lockingly retained therein, with the plug-in section (11;31) having at least one recess (13;33) provided with an undercut and a largest diameter of which corresponds to a diameter of a stem (15) of the expansion member (14) for enabling the closing member (9;29) to eclipse the shaft (15) of the expansion member (14).

Abstract: A cover for a bolt and an annular nut having a plurality of generally planar, side surfaces. The cover includes: a shell having a closed end portion and a plurality of side surfaces extending downwardly from the closed end portion, an interior portion of said side surfaces being threaded; and a clip for inserting into the aforementioned shell. The clip includes an annular ring and a plurality of spaced projections extending downwardly from the ring, each projection having exterior threads for engaging with the threaded interior of the shell. Preferably, interior portions of each downward clip projection has a substantially planar surface for engaging with the sides of a lug nut over which this cover is installed.

Abstract: The invention is a plastic safety cover for covering bolts and similar hardware items that may extend from construction projects such as building scaffolding. The invention is designed to be used to cover bolts etc. that extend outward from scaffolding found on construction sites urban areas. The cover may use commercially sold plastic caps that are typically in use on many items sold in retail. The cover should have a series of weep holes in order to permit drainage of water from the cover and should have an aperture cut in the top wall in order to accommodate the bolt that may protrude through the upper wall.
