Value Collection -92421-1 Hex Head Cap Screw 18-8 Ss

Product Description

The VALUE COLLECTION -92421-1 is a hex head cap screw designed for general-purpose fastening in industrial, mechanical, and structural applications. Manufactured from 18-8 stainless steel, it provides corrosion resistance suitable for wet, outdoor, and mildly corrosive environments. The fastener features a 1-8 thread size (UNC) with a 3-1/2 inch length under head, making it appropriate for through-bolting thicker assemblies where a standard hex wrench or socket is used to drive the fastener. This screw is a reliable option for tradespeople and maintenance professionals working with inch-series hardware.

This hex head cap screw is suited for a wide range of applications including equipment mounting, HVAC frame assembly, plumbing fixture installation, electrical enclosure fabrication, and general mechanical maintenance. The 18-8 stainless steel grade makes it a common choice where mild corrosion resistance is needed without stepping up to a higher alloy. It is used in both residential and light commercial settings wherever a UNC inch-series fastener of this size is called for.

Key Features

• 18-8 stainless steel construction provides corrosion resistance in wet and outdoor environments
• 1-8 UNC thread standard for compatibility with standard inch-series nuts and tapped holes
• 3-1/2 inch length under head suitable for through-bolting thicker material assemblies
• Hex head drive style accepts standard hex wrenches and sockets
• Inch system of measurement for use with imperial tooling and hardware

Compatibility

Designed as a standard inch-series UNC hex head cap screw for use wherever a 1-8 x 3-1/2 inch fastener in 18-8 stainless steel is required.

Installation Notes

Installation is typically performed by maintenance technicians, millwrights, or tradespeople using a standard hex wrench or socket set. Ensure mating threads are clean and free of debris before installation. Do not overtighten stainless steel fasteners, as the material is susceptible to galling — apply an appropriate anti-seize compound when assembling stainless-to-stainless joints. Follow applicable mechanical and structural codes for fastener torque and joint requirements.
