Value Collection R40684431 Hex Socket Cap Screw 1/2-13

Product Description

The VALUE COLLECTION R40684431 is a hex socket cap screw designed for fastening applications requiring a clean, recessed drive and reliable clamping force. It features a 1/2-13 UNC thread, a 3/4-inch length under head, and is driven by a 3/8-inch hex key. Constructed from 18-8 stainless steel, it offers solid corrosion resistance in wet, outdoor, and chemically exposed environments. This fastener suits mechanical, structural, and equipment assembly work across a range of trades and industrial settings.

This screw is well suited for use in HVAC equipment assemblies, plumbing fixture mounting, electrical enclosure hardware, and general trade fabrication where a flush or recessed cap screw is preferred over a hex head fastener. The 1/2-13 UNC coarse thread provides reliable engagement in tapped steel, aluminum, or stainless mating parts. Installers working in corrosive or high-moisture environments will benefit from the 18-8 stainless steel construction.

Key Features

• 1/2-13 UNC coarse thread for broad compatibility with standard tapped holes
• 3/4-inch length under head for controlled fastening depth
• 3/8-inch hex socket drive for use with standard Allen keys or hex bit drivers
• 18-8 stainless steel construction for corrosion resistance in wet and outdoor environments
• Low-profile socket cap head for recessed or close-clearance installations

Compatibility

Designed as a standard 1/2-13 UNC hex socket cap screw for use in any application requiring this thread form and drive type.

Installation Notes

Install using a calibrated hex key or hex bit driver sized to 3/8 inch. Ensure the mating tapped hole is clean and free of debris before driving. Do not over-torque stainless steel fasteners, as galling can occur; applying anti-seize compound to the threads is recommended in stainless-to-stainless assemblies. Follow applicable mechanical or structural codes for torque specifications based on joint design.
