Value Collection 198792 Hex Socket Cap Screw 5/16-18 Unc

Product Description

The VALUE COLLECTION 198792 is a fully threaded hex socket cap screw designed for fastening applications that demand corrosion resistance and precise torque control. Sized at 5/16-18 UNC with a 1-1/2 inch length under head, it is driven by a 1/4 inch hex key. Constructed from 18-8 stainless steel, this fastener resists rust and oxidation in wet, chemical-exposed, or outdoor environments. It is well suited for mechanical assemblies, equipment mounting, and structural connections where a recessed drive profile is preferred over external hex heads. Licensed tradespeople and maintenance technicians working across plumbing, HVAC, electrical, and pool service applications commonly specify stainless socket cap screws where tool clearance is limited.

This fastener fits residential and commercial applications requiring a compact, low-profile head with reliable clamping force. The 5/16-18 UNC coarse thread engages quickly into tapped holes and standard threaded inserts. Its full thread length along the 1-1/2 inch shank maximizes thread engagement, which is particularly useful in thin-material or shallow-boss installations. Stainless steel construction makes it appropriate for pump enclosures, conduit supports, heat exchanger brackets, and pool equipment frames where moisture exposure is routine.

Key Features

• 5/16-18 UNC coarse thread for fast engagement in standard tapped holes
• 1-1/2 inch length under head for adequate thread engagement in a range of material thicknesses
• Fully threaded shank for maximum grip across the entire fastener length
• 18-8 stainless steel construction for corrosion resistance in wet and chemical environments
• 1/4 inch hex drive allows installation with standard hex keys and socket drivers in confined spaces

Compatibility

Designed as a standard 5/16-18 UNC hex socket cap screw suitable for use wherever this thread size and drive type are specified in mechanical, HVAC, plumbing, electrical, and pool equipment assemblies.

Installation Notes

Install using a 1/4 inch hex key or Allen-type socket driver. Ensure the mating tapped hole is clean and free of debris before threading to avoid cross-threading or galling, which is a known risk with stainless fasteners. Apply an anti-seize compound when threading stainless steel into stainless steel to prevent galling during installation or future removal. Power down or de-energize any equipment before fastening components in electrical or HVAC assemblies.
