Nylon 6/6 Machine Screw, Plain Finish, Off-White, Round Head, Slotted Drive, Meets ASTM D4066/ASTM D6779, 1/2" Length, Fully Threaded, #4-40 Threads (Pack of 100)

The off-white nylon 6/6 machine screw has a round head with a slotted drive, and meets American Society for Testing and Materials ASTM D4066 and D6779 specifications. Nylon 6/6 provides resistance to abrasion, corrosion, and many chemicals and solvents. The material is a strong yet lightweight plastic and is nonconductive. Nylon 6/6 can either absorb or lose moisture, which may alter its dimensions and mechanical properties. The slotted drive has a linear slot for use with a flat-blade driver. The round head has a domed shape. Machine screws are threaded fasteners that are typically used with nuts or drilled and tapped (threaded) holes. Machine screws are available with a variety of head shapes, which determine how the screw interacts with the mating surface, and drive styles, which determine the type of driver required to install and remove the screw.
