Abstract: A drilling tapping screw includes a head engageable with rotary fastening tool, and a shank extending downward from the head and having a lower end having with a drilling tip, including a tapping and fastening thread defined from the end face thereof to the head. The head includes a pointed projection, an engaging portion engageable with the rotary fastening tool, and a collar. The pointed projection consists of a first tapered portion with a conical top end, a shaft with a fixed outer diameter, and a second tapered portion formed in the wake of the latter. Frame members made of steel are first firmly fastened by the screw, and joined to a wallboard, so that all the head portions except the collar stab the wallboard by striking with a hammer the site where the head is positioned. This temporarily locks the wallboard and prevent any warping of the site where the head is positioned in the wallboard.

Abstract: A deck-retaining clamp assembly secures a corrugated deck panel to a support cable that underlies and supports the deck panel, the deck panel having in a lower web portion an elongated opening that overlies a segment of the support cable and extends transversely of the support cable. A U-bolt engages the cable from below, and a clamp plate is tightened against the upper surface of the deck panel by at least one nut threaded onto one leg of the U-bolt. A handle attached to one of the legs of the U-bolt permits manipulation of the U-bolt to engage it with the support cable. The handle has a grip portion that is shaped and dimensioned such that it cannot pass through the hole in the clamp plate and a shank portion that is movable through the hole in the clamp plate and is of a length such that the U-bolt can be moved down relative to the clamp plate to a position such that the upper end of the U-bolt is at a level below the lowermost extremity of the support cable.

Abstract: A pipe clamp with a headed bolt for securing a pipe connection, in particular pipes of the exhaust system of a motor vehicle which are to be connected to one another, in the case of which the end of a first pipe is pushed into an axially slit end of a second pipe and, when the headed bolt is tightened, the pipe clamp, fitted on the slit pipe end, connects the two pipe ends to one another in a frictionally locking manner, is to be secured against a reduction in clamping force. For this purpose, the pipe clamp is formed of a material which has a higher coefficient of expansion than does the material of the pipes which are to be connected. The head of the headed bolt is elongated, in order to avoid impermissibly high local stressing during tightening of the pipe clamp. Due to the elongate form of the head of a headed bolt, the forces on the pipe clamp which support the tightening torque are reduced by a lengthening of the lever arm with respect to the axis of the headed bolt.

Abstract: The invention contemplates a compression wire for fixated retention of a fractured small bone fragment in an osteosynthesis procedure. The wire comprises a smooth-walled shank portion and an adjoining threaded portion, of lesser diameter than the diameter of the shank portion, there being a step-down shoulder between the shank portion and the threaded portion. The shank portion is adapted for chucked engagement to a portable rotary drill, and the distal end of the threaded portion is configured for self-tapping entry into and threaded implantation in bone. The implantation is complete when the shoulder engages cortex tissue of the fragment, holding the same in compression against remainder structure of the fractured bone. Once implanted, the shank may be nipped by a cutter tool at relatively close offset from the shoulder.

Abstract: A self-drilling stud particularly suited for use in normal weight or lightweight composite deck system where the use of standard weld studs is inappropriate because of the relatively thin material cross-section of the steel support member. The stud is heat treated to a dual-hardness level so that a portion of the stud is capable of drilling the support member and the decking. The remaining portion of the stud remains relatively ductile so that it can withstand and transfer shear loads imposed by shifting of the concrete slab which overlies the decking to the main support members. The stud is a single piece fastener which includes specially formed annular flanges which enhance interlocking between the stud, the concrete slab and support members.

Abstract: A side beam pipe hanging bracket for principal use in fire sprinkler systems. In the first step of forming the bracket, a generally rectangular shape having an inverted-T-shaped slot, is cut from the metal strip, thereby defining a bolt receiving segment and two hanging segments, one to each side of the bolt receiving segment. The flat bracket is then stamped with threads along the bolt receiving segment, thereby causing the bolt receiving segment to curve and the hanging segments to move laterally toward one another. The hanging segments are then forced further laterally until they overlap one another and holes in each segment are aligned. This motion causes the bolt receiving segment to bend further into a channel with threads around its inner circumference capable of accepting a threaded pipe hanging rod. The bracket is mounted on the vertical surface of a horizontal support by extending a fastener through the overlapped holes in each hanging segment.

Abstract: A steady pin, which is renovated from a push pin, contains a threaded stem and an elliptical cylinder head with a vertical concave periphery surface. The threaded stem can provide the steady pin with a better horizontal load holding capability and a better tacking repetability at the same tacked position on a wall or a board when the steady pin is tacked by a user. The elliptical head of the steady pin can generate a proper amount of torque on a steady pin by user's thumb and index finger such that the rotating motion of the steady pin is easy to be performed. The vertical concave periphery surface on the steady pin head is utilized to generate a vertical force from the user's fingers to push the steady pin into or pull the steady pin out of a wall, bulletin, or notice board.

A second elongated stud is externally threaded at both ends while an internally threaded collar threadably engages the external threads on the first stud and one end of the second stud when the studs are axially aligned and adjacent each other. A non circular projection extends axially outwardly from one end of one stud and is received within a like shaped recess on the end of the other stud to prevent the studs from rotation relative to each other.

Abstract: The anchor includes a stud holder having one end which threadably receives a threaded stud. A flat tongue-like driving head projects axially from the other end of the stud holder and is formed with an eye for receiving one end portion of a wire tie for establishing a positive lateral load connection between an outer masonry veneer wall and an inner supportive wall having a layer of insulation thereon. An integral, radially extending flange is formed at the inner end of the driving head and stabilizes the stud holder while the latter is being driven by a power-rotated socket. When the stud is fully driven, the flange seals a hole drilled in the insulation by the stud holder. The inner end of the stud holder includes cutting elements which enable the stud holder to drill effectively through both hard and soft insulation. The eye through the driving head is shaped so as to eliminate the need of establishing precise angular alinement between the driving head and the wire tie.

Abstract: A T-shaped bolt for use in securing two slotted members--such as an upright post and a horizontal beam in a pallet storage rack--to each other. The tee head of the bolt is dimensioned to be inserted in a pair of aligned slots of the two members that are to be secured to each other, and then rotated so that the ends of the tee head abut edge portions of the slot in the first slotted member, with the threaded shank of the bolt extending out through the slot in the second slotted member. The nut to be threaded on the bolt is a torque resistant nut, and thus when it is first turned it will cause the bolt to rotate until its specially shaped neck abuts the edges of one or both slots. At this point, the application of a predetermined minimum torque causes the nut to be turned further upon the bolt, until it is turned up tight against the second member and secures the two slotted members to each other.
