Value Collection 204080 Hex Cap Screw 1/2-13 316 Ss

Product Description

The VALUE COLLECTION 204080 is a partially threaded hex head cap screw designed for fastening applications that require corrosion resistance and reliable clamping strength. Sized at 1/2-13 (UNC thread) with a 3-1/2-inch length under head, this screw is manufactured from Grade 316 stainless steel and left uncoated to preserve the natural corrosion resistance of the alloy. The 1/2-13 UNC thread specification is a standard Inch-system designation widely used across mechanical, structural, and industrial assemblies. Machinists, maintenance mechanics, pipefitters, and millwrights routinely specify 316 stainless fasteners where moisture, chemical exposure, or outdoor environments are factors.

This fastener is suited for use in marine environments, chemical processing equipment, food service infrastructure, HVAC equipment frames, plumbing infrastructure, and similar installations where standard carbon steel fasteners would corrode prematurely. The partially threaded shank allows for a smooth bearing surface in the grip area, which is appropriate for applications requiring precise load distribution or joint alignment before threads engage. Sold individually, with a minimum order quantity of 25 pieces per order.

Key Features

• Grade 316 stainless steel construction for superior corrosion and chemical resistance
• 1/2-13 UNC thread form, Inch measurement system
• 3-1/2-inch length under head for use in deeper fastening applications
• Partially threaded shank provides a smooth grip section for improved load transfer
• Uncoated finish retains the inherent properties of 316 stainless alloy
• Hex head drive for use with standard hex wrenches and sockets

Compatibility

Designed as a standard 1/2-13 UNC Inch-series hex head cap screw suitable for use in any application calling for a 1/2-13 partially threaded fastener in Grade 316 stainless steel.

Installation Notes

Installation is typically performed by mechanics, pipefitters, or maintenance technicians using a standard hex socket or open-end wrench sized for a 1/2-inch fastener. De-energize or depressurize any equipment before replacing structural fasteners. Apply an anti-seize compound compatible with stainless steel to prevent galling, which is a common issue when threading stainless fasteners under torque. Follow applicable torque specifications from the equipment manufacturer or relevant ASME or ASTM standards for the joint being assembled.
