Value Collection 592493BR Hex Socket Cap Screw 1-8 Unc

Product Description

The VALUE COLLECTION 592493BR is a fully threaded hex socket cap screw designed for high-strength fastening in demanding industrial and mechanical applications. Built from 18-8 austenitic stainless steel (Material Grade A2), this fastener resists corrosion without a surface coating, making it well suited for environments where rust resistance and clean aesthetics matter. The screw features a 1-8 UNC thread size, a 2.25-inch length under head, and accepts a 3/4-inch hex drive. It meets ASME/ANSI B18.3 and ASTM F837 standards, confirming dimensional and performance compliance for critical assemblies.

This hex socket cap screw is used in general mechanical assembly, machine building, maintenance and repair operations, and structural fastening where a recessed drive is preferred. The socket cap head profile allows for installation in tight clearance areas where a wrench-drive fastener would not fit. It is appropriate for both indoor and corrosion-exposed applications where stainless steel is specified. Sold individually, it is suitable for low-volume repair work or replacement of a single fastener in an existing assembly.

Key Features

• 1-8 UNC thread size for coarse-thread engagement in standard tapped holes
• Fully threaded 2.25-inch length under head for maximum thread engagement
• 3/4-inch hex socket drive for use with standard hex keys or socket drivers
• 18-8 austenitic stainless steel, Material Grade A2, for corrosion resistance
• Bright/uncoated finish with no added plating or chemical treatment
• Meets ASME/ANSI B18.3 and ASTM F837 dimensional and material standards

Compatibility

Designed as an OEM-style replacement or standard-fit hex socket cap screw for any application requiring a 1-8 UNC fully threaded fastener with a 2.25-inch length under head and a 3/4-inch hex drive.

Installation Notes

Installation is typically performed by machinists, maintenance technicians, or mechanical contractors using a calibrated hex key or socket wrench. Verify that the mating tapped hole is clean and free of debris before threading. Do not cross-thread or over-torque; follow the torque specifications published by your assembly engineer or applicable industry standard for 18-8 stainless fasteners. Stainless steel fasteners can gall under high-speed or high-torque installation, so use a thread lubricant or anti-seize compound where appropriate.
