Value Collection 1738 Hex Head Cap Screw 3/8-16 X 3 in 18-8 Ss

Product Description

The VALUE COLLECTION 1738 is a 3/8-16 hex head cap screw machined from 18-8 stainless steel. It measures 3 inches under the head and uses a Unified National Coarse (UNC) thread form, with a 9/16-inch hex drive. The 18-8 stainless steel construction provides corrosion resistance in wet, humid, and mildly chemical environments. This fastener is installed using a standard hex wrench or socket and is suited for structural and mechanical assembly applications where corrosion resistance is a priority. Plumbers, HVAC technicians, electricians, and general contractors commonly use stainless hex cap screws in equipment mounting, pipe support, and panel assembly work.

This screw is appropriate for use in residential and light commercial applications where a coarse-thread stainless fastener is required. Typical use cases include equipment brackets, duct supports, electrical enclosures, pump mounts, and general mechanical assemblies exposed to moisture or outdoor conditions. The UNC thread form is the most widely used coarse-thread standard in inch-based fastener applications, making this screw compatible with standard tapped holes and hex nuts of the same thread designation.

Key Features

• 18-8 stainless steel construction resists corrosion in wet and humid environments
• 3/8-16 UNC thread form fits standard inch-system tapped holes and nuts
• 3-inch length under head suits medium-depth fastening applications
• 9/16-inch hex drive compatible with standard wrenches and sockets
• Inch measurement system for direct replacement in UNC-threaded assemblies

Compatibility

Designed as a standard inch-system UNC hex head cap screw for use in any application requiring a 3/8-16 threaded fastener in 18-8 stainless steel.

Installation Notes

This fastener is installed by hand-threading into a properly tapped 3/8-16 UNC hole, then tightening with a 9/16-inch wrench or socket. De-energize and isolate any equipment before fastening work near electrical or mechanical systems. Do not exceed the material yield strength of 18-8 stainless steel when torquing, and avoid mixing stainless hardware with dissimilar metals in corrosive environments to prevent galvanic corrosion. Follow applicable codes and equipment manufacturer guidelines for fastener torque and installation procedures.
