Machine Screws are uniformly threaded screws designed to be threaded into uniformly mating threaded nuts (or threaded holes) in the parts they are intended to fasten. Typically available from micro sizes 00 (0.047) up to 38 diameter (metric sizes also available). Shorter lengths are most common, but lengths can be up to 3. Due to their relative size and strength, they can easily be differentiated from larger, stronger bolts. Additionally, driving (turning) the slotted or recessed head of the screw to tighten the fastening joint is common to machine screws.A machine screw thread is defined by it thread size (diameter) and the number of threads per inch, followed by the thread form call out; UNC for coarse, UNF for fine, and the most common class of fit 2A for external thread.As the name implies, a machine screw is used to fasten various components together in machines, hand tools, white good, vehicles and many other applications. They are available in virtually any material, with the most common being steel, brass and stainless steel. The applicable standard is ANSI AMSE B.18.6.3.DRIVE STYLES: Slotted, Phillips, Combo, Torx, and External Hex are the most common. Other drive styles are available and can be made to order.HEAD STYLES: Pan, Round, Truss, Hex, Hex Washer, Binding, FillisterMATERIAL OPTIONS: Zinc, Zinc Trivalent, Nickel, Chrome, and Black Oxide are the most common. Other material options are available and can be made to order.OTHER OPTIONS: Painted heads to match decorative or painted finishesAdhesive locking patches to prevent loosening.

Plastics have become an important part of industry over the last fifty years. Improvements in technology resulted in hundreds of different plastics being created to serve a variety of purposes. Earlier fastener thread designs for plastic such as type B tapping screws or 25 (BT) thread cutting screws were no longer suitable for assembly in the new plastic materials. Not only did fastener manufacturers make improvements to existing thread designs, but they also developed many new concepts to solve the unique problems of joining plastics.Over a generation some of these designs gained acceptance and approval from fastener consumers all around the world. From among the most proven, successful designs, Fasco offers standard and customer variations of these products: PT, Delta PT and Duro PT (originated by EJOT), Plastite, Remform (originated by Reminc), Hi-Lo DST dual spaced thread (originated by ITW Shakeproof).DRIVE STYLES: Phillips, Pozidriv, Torx, Torx Plus, and Torx Autosert are the most common. Other drive styles are available and can be made to order.HEAD STYLES: Pan, Pan Washer, Flat, and Oval. Other head styles are available and can be made to order.MATERIAL OPTIONS: 1018, 1022, 10B21, SCM 435 and 302 Stainless SteelPLATING OPTIONS: Zinc (Trivalent), Zinc Nickel Alloy, and Passivated (Stainless). Other plating options are available and can be made to order.

SEMS are threaded fasteners which combine and captivate one or more washers onto a screw. They are assembled with speed and precision, eliminating costly hand assembly and improving production efficiency and quality. The screw and washer are permanently attached, but the washer remains free spinning.Virtually any type of screw (Tapping, Machine, Thread Cutting, etc) can be combined with a variety of washers to suit any application. Sizes range from #2 through 38 (M2 through M10). The applicable standard is ANSI B18.13.Washer Types available for SEMS: Tooth (Internal, External and Combination), Helical Split, Flat, Conical, Terminal and Proprietary Designs (Square Cone, Split Flat Combo).DRIVE STYLES: Tamper Resistant, One Way, SpannerHEAD STYLES: Round

The most common bolts used for general applications.MATERIAL OPTIONS: Low Carbon Steel (Grade 2, Grade 4.6), Medium Carbon Steel (Grade 5, Grade 8.8), Alloy (Grade 8, Grade 10.9), Stainless Steel 302, 304, 316, A286, Other Materials upon request.PLATING OPTIONS: Zinc (Trivalent), Various Color Chromates, Zinc Alloys (Zinc, Tin, Zinc Nickel, Etc), Phospate and Oil, Automotive Finish (Doerken, Magni, Etc), Proprietary Finish (Dacromet, JS-500, Etc), and Passivation
