Value Collection R40684140 Hex Socket Cap Screw 1/2-13

Product Description

The VALUE COLLECTION R40684140 is a hex socket cap screw designed for fastening applications that require a recessed drive and reliable clamping force. Threaded at 1/2-13 UNC, it features a 1-inch length under the head and accepts a 3/8-inch hex (Allen) key drive. Constructed from 18-8 stainless steel, this fastener resists corrosion in wet, humid, or mildly chemical environments. It is suited for mechanical assembly, equipment fabrication, and maintenance work across industrial and trade applications. Licensed tradespeople and maintenance technicians working with structural or mechanical assemblies will find this a standard cap screw for general-purpose bolted joint use.

This socket cap screw is used in a wide range of mechanical and structural assemblies where a flush or recessed fastener head is preferred over an external hex bolt. Common applications include mounting brackets, equipment panels, pump housings, valve assemblies, and general fabrication work in HVAC, plumbing, and industrial maintenance settings. The 1/2-13 UNC thread form is a standard coarse-thread designation widely used in North American trade and manufacturing environments.

Key Features

• 1/2-13 UNC coarse thread for broad compatibility with standard tapped holes
• 1-inch length under head for moderate grip and clamping depth
• 3/8-inch hex socket drive for use with standard Allen keys or hex bit drivers
• 18-8 stainless steel construction provides corrosion resistance in wet and humid conditions
• UNSPSC Code 31161501 for procurement and catalog classification

Compatibility

Designed as a standard 1/2-13 UNC hex socket cap screw suitable for tapped holes and threaded inserts conforming to Unified National Coarse thread standards in mechanical and structural assemblies.

Installation Notes

Installation is performed with a 3/8-inch hex key or Allen-style bit driver. Ensure the mating threaded hole or nut is clean and free of debris before installation. Apply appropriate thread lubricant or anti-seize compound if required by the application environment. Do not exceed the rated torque for 1/2-13 stainless steel fasteners as specified by the joint design engineer, and avoid over-torquing, which can gall stainless steel threads.
