Plastic Threaded Rod: PEEK, Nylon, PTFE, Vinyl Ester, Acetal and Ultem®

What is Plastic Threaded Rod?
Plastic threaded rod, also referred to as a stud, is a bar of round plastic material threaded in a helical structure. It is used to convert between rotational and linear movement or force. Threaded rod creates a strong resistance to pressure and tension. The direction of the rotation the threaded rod creates depends on whether the rod has a right-hand thread or a left hand thread.
It is used to align support systems. … Read more

PEEK Medical Implants

Medical Implants
PEEK or polyetheretherketone is a high performance, engineered plastic. It is one of the materials of choice for spinal implants as well as trauma fixation. Trauma fixation is the repair of broken bones or any bodily injury that can result from force or violence applied to the human body. It is also used for cardiovascular implants as well as in orthopedic surgery and dentistry. While in the past, metals such as titanium have often been used for these purposes, … Read more

Teflon® (PTFE) Screws, Hex Huts, Hex Head Cap Screws, Other Fasteners and Custom Parts

Teflon® (PTFE) Fasteners
Teflon® (PTFE) is fabricated into fasteners.  These include screws, hex nuts, hex head cap screws, flat washers etc. It is also used to fabricate custom parts.  However, this material can only be turned, or made into parts on a CNC machine. It can also be compression molded. But it cannot be injection molded.  It is not a thermoplastic.
These fasteners and custom parts are used in applications where high heat and chemical resistance are required.  … Read more
