Value Collection 2-H-50C-325 Hex Head Cap Screw 1/2-13

Product Description

The VALUE COLLECTION 2-H-50C-325 is a partially threaded hex head cap screw sized 1/2-13 x 3-1/4 inches, manufactured from Grade 316 stainless steel with a bright, uncoated finish. Grade 316 stainless steel provides superior corrosion resistance compared to Grade 304, making it well suited for wet, chemical, or marine environments. The 1/2-13 designation indicates a 1/2-inch nominal diameter with 13 threads per inch on the Unified National Coarse thread form. This fastener is installed by licensed contractors, pipefitters, plumbers, and maintenance mechanics in a wide range of commercial and industrial applications.

This cap screw is used in structural, mechanical, and process-piping assemblies where corrosion resistance is a priority. Typical applications include mounting flanges, securing pump housings, anchoring equipment in food-processing or marine environments, and general mechanical assembly requiring a reliable, corrosion-resistant fastener. The partial threading allows the shank to bear shear loads while the threaded portion draws mating components together.

Key Features

• Grade 316 stainless steel construction for enhanced corrosion and chemical resistance
• 1/2-13 UNC thread form, 3-1/4 inch length under head
• Partially threaded shank for shear-load applications
• Bright, uncoated finish — no galvanic interference from plating
• Inch-measurement system for compatibility with standard SAE tooling

Compatibility

Designed as a standard 1/2-13 UNC hex head cap screw for use in any application requiring a Grade 316 stainless steel partially threaded fastener in the inch-measurement system.

Installation Notes

This fastener should be installed by qualified tradespeople using calibrated torque tooling appropriate to the joint design and applicable standards. De-energize and depressurize any system before replacing fasteners on live equipment. Apply anti-seize compound appropriate for stainless steel to prevent galling, as 316 SS fasteners are susceptible to thread galling when driven under high friction without lubrication. Follow applicable mechanical and structural codes for torque values and fastener specifications.
