Value Collection 592491BR Hex Socket Cap Screw 1-8 Unc

Product Description

The VALUE COLLECTION 592491BR is a hex socket cap screw designed for fastening applications that require high corrosion resistance and reliable clamping force. It features a 1-8 UNC thread and measures 2 inches in length under the head. The screw is fully threaded from the head to the end, providing maximum thread engagement throughout the fastened joint. Drive engagement is achieved with a 3/4-inch hex key. Made from 18-8 austenitic stainless steel with a bright, uncoated finish, this fastener is suited for use in wet, chemical-exposure, or food-service environments where carbon steel would corrode. Machinists, millwrights, and maintenance mechanics are the typical installers.

This screw is used across general industrial, mechanical assembly, and maintenance applications. The 1-8 UNC coarse thread is a standard fastener size found in machine frames, equipment housings, fixtures, and fabricated assemblies. Full threading makes it especially useful in through-hole applications or when threading into nuts rather than tapped blind holes. The 18-8 stainless construction meets ASME/ANSI B18.3 and ASTM F837 standards, making it appropriate for regulated or specification-driven projects in food processing, marine, and general industrial settings.

Key Features

• 1-8 UNC coarse thread for standard imperial fastening applications
• 2-inch length under head provides solid grip depth in through-hole and tapped assemblies
• Fully threaded shank maximizes thread engagement in nuts and through-holes
• 3/4-inch hex socket drive for use with standard hex keys or allen wrenches
• 18-8 austenitic stainless steel (Material Grade A2) resists rust and corrosion
• Bright uncoated finish meets ASME/ANSI B18.3 and ASTM F837 standards

Compatibility

Designed as a direct-fit replacement or standard-spec fastener for any application calling for a 1-8 UNC hex socket cap screw with a 2-inch length under head in 18-8 stainless steel per ASME/ANSI B18.3 and ASTM F837.

Installation Notes

Installation should be performed by a qualified mechanic or millwright familiar with inch-series fastener standards. Ensure the mating tapped hole or nut is clean and free of debris before assembly. Use a calibrated torque wrench with a 3/4-inch hex bit to achieve proper clamp load without over-driving the fastener. Do not mix stainless steel fasteners with dissimilar metals in environments where galvanic corrosion is a concern without appropriate isolation measures.
