Drywall anchor screws is one piece self-drilling anchor designed for use in hollow gypsum wallboard for light duty loads.It is available in both engineered nylon and zamac alloy for use with either a No.6 or No.8 screws in 3/8" to 1" wallboard.The drywall anchor screws is formed from engineered nylon for use with No.6 screw in 3/8"to 5/8" wallboard.Application:1�First,we neeed to use electric drill to drill specific size of the hole2�Second,putting zinc-alloy speed anchors in the hole.3�Finally,using a screw driver to tighten screw into the expansion tube unitil the specified location.Features: 1. Ideal for mounting electrical fixtures ,fastening drapery supports,installing phone systems,miscellaneous hardware,etc2. Packaged and offered with and without screw. Installation: 1. Insert wither No.2 or No.3 Phillips driver bit into the recess of the zamac alloy anchor head.Use a manual screwdriver or a low rpm battery powered electric screw gun.2. Push the anchor into the surface of the wallboard until the two cutting bladed penetrate the surface.Using gentle forward pressure,rotate the anchor until the collar sets flush to the sueface of the wall.3. Put the fixture in place,insert the screw and tighten until it feels secure.As the screw is threaded into the nylon versions,the point will expand resulting in increased load capacity in thicker wallboard.Note: When use a n electric screw gun for application,set clutch and use slow speed(do not exceed approximately 300-400rpm)

GM Hydraulic Throwout Bearing Assembly Method
Because bearings are high-precision products, improper assembly can easily cause damage to the bearing grooves and lead to bearing damage. The jeep tj throwout bearing should be assembled with special molds, and should not be knocked at will. Only small circles can be pressed into the shaft, and only large circles can be pressed when pressing large circles. When assembling, air pressure or hydraulic pressure should be used, and the upper and lower die should be horizontal when press-fitting.
