Value Collection 592263PR Hex Socket Cap Screw 1/4-20 Unc

Product Description

The VALUE COLLECTION 592263PR is a hex socket cap screw threaded to the 1/4-20 UNC standard with a 3-inch length under the head. It is partially threaded, which concentrates clamping force in the unthreaded shank and is appropriate for applications where precise fastener grip length matters. Fabricated from 18-8 austenitic stainless steel in an uncoated bright finish, the fastener resists corrosion in wet, outdoor, or chemically exposed environments. The 3/16-inch hex drive accepts a standard Allen wrench or hex bit driver. This screw is installed by electricians, plumbers, HVAC technicians, millwrights, and general trade professionals wherever a reliable stainless socket cap screw is required.

This fastener suits light to medium-duty mechanical assemblies, panel mounting, equipment framing, and fixture attachment in commercial and industrial settings. The 1/4-20 UNC coarse thread engages standard 1/4-20 tapped holes and nuts found throughout trade equipment. Partial threading makes it well suited for through-bolt applications where a clamping shank is preferred over a fully threaded body. The bright uncoated finish is appropriate for stainless-to-stainless assemblies or where a painted or plated coating would be undesirable.

Key Features

• 1/4-20 UNC coarse thread — compatible with standard 1/4-20 tapped holes and nuts
• 3 inches length under head with partial threading for controlled grip length
• 18-8 austenitic stainless steel (Grade A2) for corrosion resistance
• 3/16-inch hex socket drive for Allen wrench or hex bit installation
• Bright uncoated finish — no plating to chip, flake, or contaminate
• Meets ASME/ANSI B18.3 and ASTM F837 fastener standards

Compatibility

Designed for use in any application requiring a 1/4-20 UNC partially threaded hex socket cap screw with a 3-inch length under head. Fits standard 1/4-20 tapped holes and is interchangeable with other ASME/ANSI B18.3 and ASTM F837 compliant fasteners of the same thread and length specification.

Installation Notes

Installation requires a 3/16-inch hex key or Allen-style bit driver. Ensure the tapped hole or nut thread is clean and free of debris before driving the fastener. Do not exceed the rated torque range for 1/4-20 stainless fasteners, as over-torquing 18-8 stainless can cause galling — apply a compatible anti-seize compound when threading stainless into stainless. Power down or de-energize any equipment before accessing fastened assemblies in electrical or mechanical enclosures.
