Value Collection R40691249 Hex Socket Cap Screw 5/16-24 Unf

Product Description

The VALUE COLLECTION R40691249 is a hex socket cap screw designed for threaded fastening applications requiring a clean, recessed drive interface. This fastener features a 5/16-24 UNF thread profile, a 2-inch length under the head, and a 1/4-inch internal hex drive. It is manufactured from 18-8 stainless steel, providing corrosion resistance suitable for use in wet, outdoor, or chemically exposed environments. Installers and maintenance technicians across mechanical, plumbing, electrical, and HVAC trades reach for socket cap screws when clearance is tight and a hex key or Allen-style driver is the preferred tool.

This screw is suited for light to medium mechanical assemblies where a fine-thread fastener is required for precise clamping force and vibration resistance. The 5/16-24 UNF fine thread pitch offers tighter thread engagement compared to coarse-thread equivalents, making it appropriate for metal-to-metal connections in equipment panels, brackets, pump assemblies, and similar hardware applications. The 18-8 stainless steel construction makes it a practical choice for both indoor mechanical rooms and exposed outdoor installations.

Key Features

• 5/16-24 UNF fine thread for precise engagement and vibration-resistant clamping
• 2-inch length under head suits medium-depth fastening applications
• 1/4-inch internal hex drive compatible with standard Allen keys and hex bit drivers
• 18-8 stainless steel construction provides corrosion and oxidation resistance
• Recessed socket head allows flush or near-flush installation in counterbored holes

Compatibility

Designed as an OEM-style replacement or standard hardware fastener for assemblies requiring a 5/16-24 UNF hex socket cap screw in 18-8 stainless steel.

Installation Notes

Install using a calibrated torque wrench or hex key to avoid stripping the socket drive or over-stressing the stainless steel shank. Power down or de-energize any equipment before disassembly or fastener replacement. Stainless steel fasteners can be prone to galling during installation — applying an anti-seize compound to the threads is a common field practice. Verify thread engagement depth in the receiving component before torquing to final specification.
