Abstract: A fastener is adapted to fasten a wheel rim to a wheel hub. The wheel rim has multiple hole-defining walls respectively defining multiple installation holes. The fastener includes a main body and a sleeve. The main body extends along a central axis thereof, is adapted to engage the wheel hub, and has an abutting portion corresponding in shape to a corresponding one of the installation holes and extending into the corresponding installation hole. The sleeve is sleeved and retained on the abutting portion, and has a contacting surface, which abuts against corresponding one of the installation holes.

Abstract: A measuring device is adapted for determining a safety thread length LS of a fastener required for fastening a wheel onto a wheel hub unit. The measuring device includes an elongated measuring rod, a positioning member secured to a front end of the measuring rod and configured to abut against a circumferential abutment seat of the wheel, and a plurality of modular sleeves, each configured to be sleevably positioned on and matched up with the measuring rod. Subsequent to bringing the positioning member to abut against the circumferential abutment seat, the modular sleeve is dragged forwardly until a front sleeve end reaches an inner major surface of the wheel, and LS is determined to be equal to the distance between the front end and a rear sleeve end of the modular sleeve.

Abstract: A fastening device is adapted for securing a wheel rim to a vehicle axle and is adapted to be driven rotatably by a driving tool. The fastening device includes a fastening member and a protection cap. The fastening member has a tool-engaging head portion and a first positioning portion. The protection cap has a cover portion and a sleeve portion that cooperates with the cover portion to cover the tool-engaging head portion and that is formed with a second positioning portion engaging removably the first positioning portion. When the protection cap is removed from the fastening member, the tool-engaging head portion of the fastening member is engageable with the driving tool.

Abstract: A fastener for securing a wheel rim to an automobile axle unit includes a shank segment, a hollow head segment and a securing pin. The shank segment has first and second threaded end portions and a smooth stop portion interconnecting the first and second threaded end portions. The head segment is formed with an internal thread engaged with the first threaded end portion, and has an abutting portion adapted to abut against the wheel rim and having a cross-section converging toward an open end thereof. The securing pin extends through the head segment into the shank segment for securing the head segment to the shank segment.

Abstract: A measuring device is adapted for determining a thread length of a fastener required for fastening a wheel onto a wheel hub unit. The measuring device includes a measuring rod extending straightly to terminate at front and rear surfaces, a positioning member secured to the front surface to mate with an abutment seat of a bolt hole in the wheel so as to measure a length of the bolt hole, and an anchor member secured to the rear surface and extending perpendicularly to be brought into abutment with a flange surface of the wheel hub unit so as to measure a thread length of a threaded bolt or bore.

Abstract: A fastener includes a socket-engaging part and a securing part. The socket-engaging part has an external surrounding surface having at least one planar surface region and formed with grooves. Edges of the grooves and the planar surface region are disposed on an imaginary hexagonal prism, in a manner that the socket-engaging part can be sleeved in a hexagonal socket wrench. One of the edges of each groove contacts a respective one of inner surface portions of the hexagonal socket wrench, and the planar surface region contacts one of the inner surface portions of the hexagonal socket wrench when the hexagonal socket wrench is sleeved on and rotated to drive rotation of the socket-engaging part. An imaginary circumscribed cylinder of the external surrounding surface has a diameter slightly shorter than that of a receiving hole of a spline socket wrench, so that the socket-engaging part can be sleeved in and driven to rotate by the spline socket wrench.

Abstract: A vehicle nut holding apparatus aims to improve the disadvantages of conventional holding apparatus that are difficult to fabricate and assemble, and cannot hold vehicle nuts securely and differentiate usage of the nuts. The holding apparatus of the invention has a plurality of housing troughs to hold a plurality of vehicle nuts. Each vehicle nut has at least one protrusive portion and one indented portion adjacent to each other. Each housing trough has a bottom and a side wall abutting the bottom. The side wall has a retaining recess corresponding to the protrusive portion and a retaining boss corresponding to the indented portion. The retaining recess is located between the retaining boss and the bottom. The retaining recess and retaining boss can retain the vehicle nut and allow the vehicle nut to be held in a displaying manner to indicate its usage.

Abstract: The present invention discloses a screw kit, which comprises: a screw element, a driving element, and an alignment element. The screw element has a screw end and a first coupling portion. The driving element has a driving end and a second coupling portion. The alignment element has a first sleeving section and a second sleeving section, which are respectively engageable with the first coupling portion and the second coupling portion. When the screw element and the driving element are simultaneously engaged with the alignment element, the deviation between the screw element and the driving element is eliminated, and the screw element and the driving element can be easily aligned to an identical axis. Thereby, the assembling and disassembling speeds of the screw element and the driving element are increased without influencing the theft-protection function thereof.

Abstract: A sectional adjustable socket tool handle, which controls the movement of an axial rod along the axial direction of an external pipe. The tool includes a plurality of grooves, a coupler for engaging the plurality of grooves, such that a latch member on the external pipe is latched into the groove under normal conditions, and the coupler can move between a first position and a second position along the axial direction of the external pipe. When the coupler moves to the first position, the coupler will press against the latch member to prevent the axial rod from moving. When the coupler moves to the second position, the coupler will release the latch member.

Abstract: A telescopic steering lock, comprising an elongated casing having a lock barrel set therein and driven to rotate by a driving bar, wherein said driving bar is set inside said lock barrel to reduce space occupation when not in use, or extended out of said casing to drive said lock barrel into a locking position; said casing has an elongated opening in longitudinal direction for mounting on the peripheral ring portion of a motor vehicle's steering wheel and a lock cylinder controlled by a key to lock said lock barrel in a locking position; said lock barrel has a tongue driven to hook in the peripheral ring portion of the motor vehicle's steering wheel into which said elongated opening is engaged.
