Value Collection 198784 Hex Socket Cap Screw 5/16-18 Unc

Product Description

The VALUE COLLECTION 198784 is a fully threaded hex socket cap screw designed for secure, high-torque fastening in demanding mechanical and structural applications. Sized at 5/16-18 UNC with a 3/4 inch length under head, it is driven with a 1/4 inch hex key. The fastener is manufactured from 18-8 stainless steel, providing solid corrosion resistance suitable for wet, outdoor, or chemically exposed environments. This screw is a standard choice for equipment assembly, bracket mounting, and maintenance tasks across HVAC, plumbing, electrical, and general mechanical trades.

This screw suits residential and light commercial applications where a compact, corrosion-resistant fastener is required. It is commonly installed in control panel assemblies, equipment housings, pipe supports, and structural brackets. The 5/16-18 UNC thread pattern is a widely used coarse thread, compatible with standard UNC tapped holes and hex-drive tooling found in most trade toolkits. Maintenance technicians and installers across multiple trades rely on this fastener for routine equipment service and new installations.

Key Features

• 5/16-18 UNC coarse thread for broad compatibility with standard tapped holes
• 3/4 inch length under head suits medium-depth fastening applications
• Fully threaded shank maximizes thread engagement across the full grip length
• 18-8 stainless steel construction resists corrosion in wet and outdoor environments
• 1/4 inch hex socket drive for use with standard hex keys and socket drivers

Compatibility

Designed as a standard 5/16-18 UNC hex socket cap screw for use in any application requiring a fully threaded stainless steel fastener driven by a 1/4 inch hex key.

Installation Notes

Installation is performed with a 1/4 inch hex key or hex bit driver. Ensure the mating tapped hole is clean and free of debris before installation. Do not overtighten stainless steel fasteners, as galling can occur — apply an appropriate anti-seize compound when fastening into stainless or aluminum threads. Follow applicable mechanical codes and equipment manufacturer torque guidelines for the specific assembly.
