Plastic Socket Head Screws

Fully Threaded

Secure parts without adding much weight. These plastic screws are also nonconductive and resist chemicals and oil. The deep, six-point socket keeps hex keys from slipping out and damaging the drive.

Length is measured from under the head.

Chemical-Resistant Polypropylene—Resist grease, acids, and alkalis better than nylon screws.
