Brass Heat-Set Insert for Thermoplastics
The Zoro Select FL-832-HI-PK100 is a brass threaded insert designed for heat installation into compatible thermoplastic materials. It provides durable #8-32 coarse threads in plastic parts that would otherwise strip under load. The flanged design adds bearing surface for pull-out resistance. Supplied in a pack of one hundred pieces.
Straight Shank with Flanged Head
The straight shank measures 21/64 in overall length with a 1/4 in insert diameter and a tapered end diameter of .22 in. Installation requires a .22 in drill bit and a minimum material thickness of 5/64 in. The maximum hole diameter is .22 in. The plain finish brass body resists corrosion and ensures consistent thermal transfer during ultrasonic or heated press insertion.
Replaces Self-Tapping Screws in Plastic Housings
Use these inserts when self-tapping screws no longer hold in repeated assembly cycles or when higher clamp loads are needed. The upgrade is worth it for electronic enclosures, automotive interior clips, or consumer-goods housings where screws are removed and reinstalled. Not suited for thermoset plastics, metal substrates, or applications requiring locking thread features.
