Product Description

The off-white nylon 6/6 machine screw has a binding head with a combination Phillips 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 combination Phillips slotted drive accepts both Phillips and standard slotted drivers and is designed to allow the driver to slip out of the head when the screw has been tightened enough, helping to prevent over-tightening and damage to the thread or fastener. The binding head is a slightly undercut, low-profile head with a round top and short vertical sides. The head is shorter and wider than a pan head, enabling use in applications that would normally require a washer with the screw. The undercut feature binds wires beneath the head, making this head style a common choice for electrical applications.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.
