Value Collection 592253PR Hex Socket Cap Screw 1/4-20 Unc

Product Description

The VALUE COLLECTION 592253PR is a fully threaded hex socket cap screw designed for secure, high-torque fastening applications across mechanical, industrial, and trade assembly work. This screw features a 1/4-20 UNC thread size and measures 1-1/8 inches in length under the head. It is driven with a 3/16-inch hex key. Constructed from 18-8 austenitic stainless steel (Material Grade A2), it provides reliable corrosion resistance in wet, marine, or chemically exposed environments. This fastener meets ASME/ANSI B18.3 and ASTM F837 standards, making it suitable for applications where dimensional accuracy and material traceability matter.

This cap screw is used in light-duty to medium-duty mechanical assemblies where a low-profile, recessed-drive fastener is required. Common applications include equipment panels, HVAC component mounting brackets, plumbing fixture assemblies, electrical enclosures, and general fabrication work. The 1/4-20 UNC thread pattern is one of the most widely used coarse-thread standards in North American trade and industrial applications, ensuring broad compatibility with standard tapped holes and threaded inserts. Sold individually; minimum order quantity is 100 pieces per order.

Key Features

• 1/4-20 UNC fully threaded for maximum grip and load distribution along the full shank
• 1-1/8 inches length under head suits moderate-depth fastening tasks
• 3/16-inch hex socket drive allows precise torque application with a standard Allen key or hex bit driver
• 18-8 austenitic stainless steel (Grade A2) provides corrosion resistance in damp or chemically active environments
• Meets ASME/ANSI B18.3 and ASTM F837 fastener standards for dimensional and material compliance
• Low-profile socket head design allows installation in recessed or space-constrained locations

Compatibility

Designed as a standard 1/4-20 UNC hex socket cap screw suitable for use in any application requiring a 1/4-20 coarse-thread fastener conforming to ASME/ANSI B18.3 dimensional specifications.

Installation Notes

Installation is performed using a 3/16-inch hex key or compatible hex bit driver. Ensure the receiving hole is properly tapped to 1/4-20 UNC specification before installation. Apply thread-locking compound or anti-seize as required by the application. Stainless steel fasteners are susceptible to galling — use appropriate lubrication and avoid high-speed power driving without torque control.
