100-Pack PEEK Low Head Hex Socket Screws - M4 x 8mm - Japan Made

SPE-M4-8-LC NBK PEEK Plastic Screw - Hex Socket Low Head Bolt - M4 x 8mm - Made in Japan - Pack of 100

The SPE-M4-8-LC is a high-performance hex socket low head screw made of PEEK (Polyether Ether Ketone) - a super engineering thermoplastic known for its exceptional heat resistance, chemical resistance, and mechanical strength. This NBK fastener is manufactured in Japan to strict precision standards and is ideal for compact installations where space is limited.

With its low-profile head and non-metallic properties, it is the perfect solution for use in high-tech and corrosive environments, especially in the semiconductor, FPD, and electronics industries.
