Value Collection 837351PS Hex Socket Cap Screw 1/2-13 Unc

Product Description

The VALUE COLLECTION 837351PS is a fully threaded hex socket cap screw designed for precision fastening in mechanical, structural, and industrial assemblies. It features a 1/2-13 UNC thread size with a 3/4-inch length under the head and accepts a 5/16-inch hex drive. Constructed from alloy steel with a zinc-plated finish, it delivers solid corrosion resistance for general-purpose applications. This fastener meets ASTM B695 standards and is suited for installation by maintenance technicians, millwrights, and mechanical contractors working in both shop and field environments.

This screw is commonly used in equipment fabrication, machine assemblies, and structural connections where a flush or low-profile head is required. The internal hex drive allows high torque application in confined spaces where a standard wrench or bolt head would not fit. The fully threaded shank provides consistent thread engagement across the entire fastened length, making it appropriate for thinner stock and blind-hole applications in metalworking and general mechanical maintenance.

Key Features

• 1/2-13 UNC thread size for standard fractional fastener compatibility
• Fully threaded shank for maximum thread engagement in thin materials
• 5/16-inch hex socket drive for high-torque application in tight spaces
• Alloy steel construction for strength in demanding mechanical environments
• Zinc-plated finish meeting ASTM B695 for corrosion protection
• 3/4-inch length under head suits shallow blind-hole and through-hole installations

Compatibility

Designed as a standard 1/2-13 UNC hex socket cap screw suitable for general mechanical assemblies, equipment fabrication, and maintenance applications requiring a 5/16-inch hex drive fastener.

Installation Notes

Installation is performed with a 5/16-inch hex key or Allen-type driver; use a calibrated torque wrench where torque specifications are defined by the equipment manufacturer. Ensure mating threads are clean and free of debris before assembly. Fastener should be installed per applicable ASME or equipment OEM specifications. Do not exceed the rated drive size or substitute an alternate drive tool, as this may damage the socket recess.
