Value Collection 592499BR Hex Socket Cap Screw 1-8 Unc

Product Description

The VALUE COLLECTION 592499BR is a hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and trade service environments. The fastener features a 1-8 UNC thread size and measures 3 inches in length under the head, with full threading along that length. The drive is a 3/4-inch hex socket, suited for use with standard socket drivers and Allen-type tools. Constructed from 18-8 austenitic stainless steel (Grade A2) with a bright, uncoated finish, this screw offers solid corrosion resistance in wet, chemical-exposure, or outdoor service conditions. Machinists, millwrights, pipefitters, and general maintenance technicians are the primary users.

This screw is well suited for structural and mechanical assemblies where a flush or recessed fastener head is required. The 1-8 UNC coarse thread pitch provides strong clamping force and is compatible with standard 1-inch UNC tapped holes. Typical applications include equipment frames, pump housings, valve bodies, bracket assemblies, and similar installations where stainless steel corrosion resistance is specified. The bright uncoated finish means no plating degradation concerns in mildly acidic or high-humidity environments.

Key Features

• 1-8 UNC coarse thread for strong clamping in standard tapped holes
• 3 inches of full threaded length under head for deep engagement
• 3/4-inch hex socket drive compatible with standard hex keys and socket tools
• 18-8 austenitic stainless steel, Grade A2, for corrosion resistance in wet or chemical environments
• Bright uncoated finish — no plating to flake, chip, or degrade
• Meets ASME/ANSI B18.3 and ASTM F837 fastener standards

Compatibility

Designed as a standard 1-8 UNC hex socket cap screw for use in any application requiring a 1-inch coarse-thread fastener conforming to ASME/ANSI B18.3 and ASTM F837 specifications.

Installation Notes

Installation is performed with a 3/4-inch hex key or socket driver. Ensure the mating tapped hole is clean and free of debris before threading the fastener. Do not cross-thread or over-torque; follow the torque specifications required by the assembly manufacturer or applicable mechanical standards. Stainless steel fasteners are susceptible to galling — applying anti-seize compound to threads is a common field practice when working with stainless-to-stainless connections.
