Value Collection 208737 Hex Head Cap Screw 18-8 Ss

Product Description

The VALUE COLLECTION 208737 is a hex head cap screw manufactured from 18-8 stainless steel to inch-system dimensions. It features a 1-8 UNC (Unified National Coarse) thread and measures 3-1/2 inches under the head. The 18-8 stainless steel grade provides solid corrosion resistance, making this fastener suitable for wet, outdoor, and chemically exposed environments. The hex drive head accepts standard wrenches and sockets for straightforward installation. This screw is sold individually and is a common choice for licensed tradespeople and maintenance professionals requiring a reliable, corrosion-resistant fastener in standard inch sizing.

This cap screw is used across a broad range of trade applications including HVAC equipment mounting, plumbing fixture attachment, electrical enclosure assembly, and general mechanical maintenance. Its UNC thread form is compatible with standard inch-threaded nuts and tapped holes. The 18-8 stainless steel construction makes it appropriate for both indoor and outdoor installations where mild to moderate corrosion resistance is required. Tradespeople working on equipment exposed to moisture or chemical contact frequently specify this grade of fastener.

Installation Notes

Installation is performed by hand-starting the screw into a clean, properly tapped or nutted hole, then tightening with an appropriately sized wrench or socket driver. Always ensure the mating thread is also stainless steel or a compatible material to avoid galvanic corrosion issues. Power down or de-energize any equipment before accessing fastener locations on live electrical or mechanical systems. Follow applicable mechanical codes and equipment manufacturer guidelines for fastener torque requirements.
