5/16-18 x 3/4in Hex Washer Thread Cutting Screw

With edges designed to help penetrate material, these screws are Type F thread cutting with a hexwasher head. They require less force for insertion, making them ideal for use in materials where disruptive stresses are not wanted or when using thread-forming screws would require too much torque. When using these screws, time is saved while strength and durability increases. (TCS51634F)
