Value Collection R57001133 Hex Head Cap Screw 5/16-24

Product Description

The Value Collection R57001133 is a fully threaded hex head cap screw designed for use in precision fastening applications requiring corrosion resistance and dimensional accuracy. Manufactured from 18-8 stainless steel with a bright uncoated finish, this fastener measures 5/16-24 UNF thread size with a 2-1/2 inch length under head. The 5/16-24 designation indicates a fine-thread (UNF) profile, which provides greater tensile strength per engagement length compared to coarse-thread equivalents. It is installed by maintenance technicians, millwrights, and mechanical contractors working with inch-system assemblies where moisture exposure or chemical contact is a concern.

This cap screw is suited for light-to-medium duty mechanical assemblies in residential, commercial, and industrial environments. Typical applications include equipment mounting, bracket fastening, and panel attachment where the fine-thread UNF profile is specified. The 18-8 stainless steel construction makes it a practical choice for outdoor installations, wet mechanical rooms, pool equipment enclosures, and other environments where carbon steel fasteners would corrode. Sold individually with a minimum order quantity of 5 pieces.

Key Features

• 18-8 stainless steel construction provides strong resistance to rust and general corrosion
• Fine-thread 5/16-24 UNF profile delivers higher thread engagement strength than coarse-thread alternatives
• Fully threaded shank allows consistent clamping force along the entire fastener length
• Bright uncoated finish ensures dimensional consistency and avoids coating thickness variables
• Inch system measurement complies with standard UNF fastener specifications

Compatibility

Designed as a standard UNF inch-system hex head cap screw suitable for any mechanical assembly specifying a 5/16-24 fully threaded fastener in stainless steel.

Installation Notes

Install using a properly sized hex wrench or socket drive rated for the fastener head size. Power down or de-energize any equipment before accessing fastened panels or assemblies. Do not mix stainless steel fasteners with dissimilar metals in high-current or galvanic environments without appropriate isolation. Apply anti-seize compound when installing stainless fasteners into stainless or aluminum tapped holes to prevent galling.
