Value Collection R83926283 Hex Head Cap Screw 5/16-18x6

Product Description

The VALUE COLLECTION R83926283 is a 5/16-18 hex head cap screw with a 6-inch length under the head, manufactured from 18-8 stainless steel. The unified coarse (UNC) thread pattern provides reliable engagement in standard inch-system tapped holes. The 1/2-inch hex drive accommodates a standard hex wrench or socket. This fastener is suited for structural and mechanical assemblies where corrosion resistance is required, and it is commonly installed by maintenance technicians, pipefitters, plumbers, and general contractors working in wet or corrosive environments.

This screw is commonly used in HVAC equipment mounting, plumbing fixture attachment, pool and spa equipment framing, and general industrial applications where moisture or chemical exposure is a concern. The 18-8 stainless steel grade offers good corrosion resistance in both indoor and outdoor service conditions. It is sold individually per unit, with a minimum order quantity of 50 pieces.

Key Features

• 18-8 stainless steel construction for corrosion resistance in wet and chemically exposed environments
• 5/16-18 UNC thread for compatibility with standard inch-system tapped holes and nuts
• 6-inch length under head for deep-reach or thick-stack fastening applications
• 1/2-inch hex drive accepts standard sockets and wrenches
• Inch measurement system — no metric conversion required for standard US trade work

Compatibility

Designed as a standard inch-system hex head cap screw compatible with 5/16-18 UNC tapped holes and matching nuts in general mechanical and structural assemblies.

Installation Notes

Install using a 1/2-inch hex socket or open-end wrench. Verify that mating threads are clean and free of debris before driving to avoid galling, which is common with stainless steel fasteners. Apply an anti-seize compound to the threads when joining stainless to stainless to reduce the risk of thread seizure. Follow applicable mechanical and structural codes for torque and joint requirements specific to the assembly.
