Pan Head

8X1/4 Phillips Truss Thread Cutting Screw Type 25 Fully Threaded Zinc Bake. Thread-Cutting Type-25 screws provide excellent chip clearance. Steel: Used in molded or through holes in plastics and other soft materials. Stainless: Material into which the screw is to cut threads should have a lower hardness by 10-20 Rockwell hardness. Truss head screws are weaker than pan or round heads but preferred in applications where minimal clearance exists above the head. Modified truss heads offer low clearance and an extra large bearing surface. Commonly used to attach metal lathe to metal studs.

4-40X3/8 Phillips Pan Thread Cutting Screw Type F Fully Threaded 18 8 Stainless Steel. Thread-Cutting Type-F threaded screws are used in heavy gauge sheet metal, aluminum, zinc and lead die castings, cast iron, brass and plastic. In stainless steel, material into which the screw is to cut threads should have a lower hardness by 10-20 Rockwell hardness. Pan head screws are a common style that can substituted in most applications for round, truss or binding heads.

10-24X5/8 Phillips Pan Thread Cutting Screw Type 23 Fully Threaded 18 8 Stainless Steel. Thread-Cutting Type-23 screws provide excellent chip clearance with minimum tightening torques. Steel: Used in cast iron and zinc, aluminum die castings, and plastics. Stainless: Material into which the screw is to cut threads should have a lower hardness. Pan head screws are a common style that can substituted in most applications for round, truss or binding heads.

4X3/8 #3 HD Phillips Truss High Low Screw Fully Threaded Zinc Bake. High-Low thread for use in plastic, nylon, wood or other low-density materials. Thread design reduces driving torques, enhances resistance to thread stripping, improves pullout strength and lessens the risk of cracking the work piece. Truss head screws are weaker than pan or round heads but preferred in applications where minimal clearance exists above the head. Modified truss heads offer low clearance and an extra large bearing surface. Commonly used to attach metal lathe to metal studs.

12X4 Phillips Flat Self Drilling Screw Full Thread Zinc Bake. Self drilling screws have point to cut through material and eleiminate the need to drill a pilot hole. Flat head screws are used when protrusion of the fastener above the mating surface is unacceptable. Typically 100 degree flat or for fastening softer materials, 82 degrees flat.
