Value Collection 92421 Hex Head Cap Screw 1-8x3 18-8 Ss

Product Description

The VALUE COLLECTION 92421 is a hex head cap screw designed for general fastening applications where corrosion resistance is required. Sized at 1-8 thread by 3 inches in length under head, this fastener is manufactured from 18-8 stainless steel and follows Unified National Coarse (UNC) thread standards. The 1-1/2-inch hex drive allows installation with standard hex wrenches or socket sets. It is well suited for mechanical assemblies, equipment mounting, and structural connections in environments where exposure to moisture or mild chemicals is a concern. Licensed tradespeople and maintenance professionals working in HVAC, plumbing, and general mechanical service will find this a dependable fastening solution.

This cap screw is appropriate for use in both light commercial and residential service applications. Its UNC thread form is the most common inch-series thread standard in North American equipment, making it a straightforward fit for replacement or repair work on a wide range of assemblies. The 18-8 stainless steel grade provides a good balance of strength and corrosion resistance without the cost of higher-alloy stainless grades. It is sold in a minimum order quantity of 5 units per order.

Key Features

• 18-8 stainless steel construction for corrosion resistance in wet or outdoor environments
• 1-8 UNC thread for compatibility with the most common inch-series tapped holes in North America
• 3-inch length under head for moderate-depth fastening applications
• 1-1/2-inch hex head drive for use with standard wrenches or sockets
• Inch measurement system for direct dimensional compatibility with standard trade hardware

Compatibility

Designed as a standard inch-series UNC hex head cap screw for use in any application requiring a 1-8 thread by 3-inch fastener in 18-8 stainless steel.

Installation Notes

Installation is performed with a standard hex wrench or socket sized to the 1-1/2-inch hex head. Ensure the mating tapped hole or nut matches the 1-8 UNC thread specification before assembly. Do not mix stainless steel fasteners with dissimilar metals in highly conductive or electrochemically active environments without appropriate isolation, as galvanic corrosion may occur. Apply an anti-seize compound when threading stainless fasteners into stainless tapped holes to prevent galling.
