Metric Socket Button Head Sealing Screws

Metric Socket Button head screws have a socket recess and rounded head. Each Metric Socket Button head sealing screw is equipped with a unique, malleable and strong captive O-ring. This device delivers extraordinary results. The O-ring, which fits tightly and precisely in the groove under the screw head, acts as a total deterrent against external/internal contamination from air, water, gas and other materials. As a result, these screws will perform like never before, granting your most sensitive equipment unbeatable protection with 360 degrees of sealant while achieving metal-to-metal contact.

All parts are made from 18-8 Stainless Steel.

O-Ring Materials Available: Silicone (-SSS), Fluorosilicone (-FSS), Buna (-BSS), and Viton (-VSS).
