Value Collection 592261PR Hex Socket Cap Screw 1/4-20 Unc

Product Description

The VALUE COLLECTION 592261PR is a hex socket cap screw sized for 1/4-20 UNC thread applications. It features a 3/16-inch hex drive and a 2-3/4-inch length under the head with partial threading. Machined from 18-8 austenitic stainless steel (Grade A2), this fastener offers solid corrosion resistance in wet or chemically active environments. It conforms to ASME/ANSI B18.3 and ASTM F837 standards, making it a reliable choice for mechanical assemblies where dimensional consistency and material grade traceability matter. Plumbers, HVAC technicians, electricians, and general mechanical contractors use socket cap screws like this one in equipment panels, brackets, and structural subassemblies.

This fastener is suited for residential and light commercial mechanical installations where 1/4-20 UNC threaded fasteners are specified. Partial threading provides a smooth shank section that can improve clamp load in through-bolt applications. The hex socket drive accepts a 3/16-inch hex key or Allen-style driver bit, making it accessible in tight clearances where a standard external-hex tool cannot engage. It is a practical stock item for service vans, maintenance carts, and shop bins requiring a corrosion-resistant cap screw in a common fractional thread size.

Key Features

• 1/4-20 UNC thread size for compatibility with standard fractional fastener hardware
• 2-3/4-inch length under head suits medium-depth clamping and through-bolt assemblies
• Partial threading provides a shank section that centers the fastener and improves clamp force
• 3/16-inch hex socket drive works in confined spaces with a standard hex key or bit driver
• 18-8 austenitic stainless steel (Grade A2) resists corrosion in wet and mildly corrosive service environments
• Meets ASME/ANSI B18.3 and ASTM F837 fastener standards for dimensional and material compliance

Compatibility

Designed as a standard 1/4-20 UNC hex socket cap screw for use in any assembly or equipment requiring a Grade A2 stainless steel partially threaded cap screw of this thread size and length.

Installation Notes

Installation requires a 3/16-inch hex key or matching driver bit; ensure the tool is fully seated before applying torque to avoid rounding the socket. Follow the applicable mechanical or equipment specification for torque requirements. In stainless steel fasteners, apply an anti-galling lubricant to the threads before installation to reduce the risk of thread seizure. Always de-energize and lock out equipment before working on fastener assemblies in electrical or HVAC panels.
