Value Collection 592269PR Hex Socket Cap Screw 1/4-28 Unf

Product Description

The VALUE COLLECTION 592269PR is a fully threaded hex socket cap screw designed for precision fastening in mechanical, structural, and industrial assembly applications. Sized at 1/4-28 UNF with a 3/8-inch length under head, this screw is driven by a 3/16-inch hex key. It is manufactured from 18-8 austenitic stainless steel (Austenitic Grade A2), providing corrosion resistance suitable for both indoor and outdoor service environments. The fine thread pitch of the UNF specification makes it well suited for applications requiring higher tensile strength or tighter fastener engagement in thin-section materials. Installers across mechanical, maintenance, and light fabrication trades rely on this type of fastener for repeatable, clean assemblies.

This screw is used in a wide range of general-purpose fastening scenarios where a low-profile socket cap head is required and clearance for a standard hex wrench is limited. The fine 1/4-28 UNF thread makes it appropriate for precision equipment, instrumentation panels, fluid fittings, and similar assemblies where vibration resistance and thread engagement quality matter. It is sold individually but must be ordered in minimum quantities of 100 units per order, making it practical for shop stock, service van inventory, or small-batch production runs.

Key Features

• 1/4-28 UNF fine thread for higher tensile load and tighter engagement than coarse thread equivalents
• Fully threaded along the entire shank length under head
• 18-8 stainless steel, Austenitic Grade A2 for corrosion resistance in wet or chemically active environments
• 3/16-inch hex (Allen) drive socket cap head for use in tight-clearance installations
• Meets ASME/ANSI B18.3 and ASTM F837 fastener standards
• Minimum order quantity of 100 units supports bulk stocking for service or production use

Compatibility

Designed as an OEM-style and general-purpose replacement or stock fastener for any assembly calling for a 1/4-28 UNF fully threaded hex socket cap screw with a 3/8-inch length under head in 18-8 stainless steel.

Installation Notes

Installation is performed using a 3/16-inch hex key or Allen wrench; confirm the driver fits cleanly before applying torque to avoid rounding the socket. Ensure mating threads are clean and free of debris before driving. Do not mix stainless steel fasteners with dissimilar metals in corrosive environments without reviewing galvanic compatibility. Follow applicable ASME or equipment manufacturer torque specifications for the 1/4-28 thread class used in the assembly.
