Value Collection 204218 Hex Head Cap Screw 3/8-16

Product Description

The VALUE COLLECTION 204218 is a 3/8-16 UNC hex head cap screw with a 1-1/2 inch length under head, manufactured from Grade 316 stainless steel. Grade 316 alloy provides superior corrosion resistance compared to standard 304 stainless, making it well suited for applications exposed to moisture, chemicals, or salt air. The 9/16 inch hex drive head accepts standard hex wrenches and sockets. This fastener is sold individually and is subject to a minimum order quantity of 100 pieces per purchase. Installers and maintenance trades working in corrosive or marine-adjacent environments rely on Grade 316 hardware to maintain joint integrity over time.

This cap screw is appropriate for use in plumbing, HVAC, pool equipment, and general mechanical assemblies where corrosion resistance is a primary concern. Typical applications include mounting brackets, equipment frames, pipe supports, and panel fastening in environments with high humidity or chemical exposure. The inch-system UNC thread form is compatible with standard tapped holes and nuts in that size class.

Installation Notes

Installation of this fastener is appropriate for qualified mechanical, plumbing, or HVAC technicians. Use a properly sized 9/16 inch hex wrench or socket to drive the fastener; do not use an undersized tool that may round the head. Follow applicable torque guidelines for 3/8-16 stainless fasteners per the equipment manufacturer or relevant code. Note that stainless steel fasteners can be prone to galling during installation; applying an anti-seize compound is common practice to prevent thread damage.
