Value Collection R83926234 Hex Head Cap Screw 5/16-18

Product Description

The VALUE COLLECTION R83926234 is a hex head cap screw designed for general fastening applications requiring corrosion-resistant hardware. It features a 5/16-18 UNC thread form with a 5-inch length under head and a 1/2-inch hex drive. Constructed from grade 18-8 stainless steel, this fastener offers solid resistance to rust and oxidation in wet, outdoor, and mildly corrosive environments. It is a standard fully-threaded or partially-threaded cap screw driven with a standard hex wrench or socket, making it a common component in mechanical assemblies, plumbing fixture mounting, HVAC equipment panels, and structural bracketing work.

This hex head cap screw is suited for residential and light commercial applications where stainless steel fasteners are specified. Typical uses include mounting brackets, equipment enclosures, pipe hangers, and structural connections where standard carbon steel fasteners would be vulnerable to corrosion. The UNC thread form is compatible with standard inch-series tapped holes and hex nuts of the same thread designation, making it straightforward to source matching hardware on the job.

Key Features

• 5/16-18 UNC thread form for compatibility with standard inch-series tapped holes and nuts
• 5-inch length under head provides reach for thicker assemblies or stacked components
• 18-8 stainless steel construction resists corrosion in wet and mildly chemical environments
• 1/2-inch hex head drives with a standard hex wrench, socket, or nut driver
• Grade 18-8 material meets common specifications for corrosion-resistant fasteners in mechanical and HVAC applications

Compatibility

Designed as a standard replacement or stock fastener for any application calling for a 5/16-18 UNC hex head cap screw in 18-8 stainless steel with a 5-inch length under head.

Installation Notes

Install using a 1/2-inch hex socket or open-end wrench torqued to the value specified by the equipment manufacturer or applicable structural standards. Ensure the mating tapped hole or nut is also 5/16-18 UNC to prevent cross-threading. When installing into dissimilar metals, consider galvanic compatibility to prevent accelerated corrosion at the joint. No special tools or certifications are required, but fastener torque should follow job-specific engineering requirements where applicable.
