Value Collection 208994B Hex Head Cap Screw 5/8-11 2.5in 18-8 Ss

Product Description

The VALUE COLLECTION 208994B is a hex head cap screw designed for general fastening applications requiring corrosion resistance. Manufactured from 18-8 stainless steel, this fastener features a 5/8-11 thread size with a Unified National Coarse (UNC) thread standard and measures 2.5 inches in length under the head. The 15/16-inch hex drive allows for standard wrench or socket installation. It is suited for use in wet, chemical-exposure, or food-service environments where standard carbon steel fasteners would corrode. Plumbers, HVAC technicians, electricians, and millwrights commonly reach for 18-8 stainless hardware when assembling equipment panels, pipe supports, and mechanical enclosures.

This cap screw is used across residential and commercial trade work wherever a corrosion-resistant inch-series fastener is required. Typical applications include equipment mounting, structural panel assembly, pipe hanger installation, and general mechanical assembly in humid or corrosive environments. The UNC thread form is the most widely used inch-series thread standard, making this screw compatible with a broad range of tapped holes and standard nuts.

Key Features

• 18-8 stainless steel construction provides strong resistance to rust and corrosion
• 5/8-11 UNC thread for compatibility with standard inch-series tapped holes and nuts
• 2.5-inch length under head accommodates moderate stack-up applications
• 15/16-inch hex drive fits standard sockets and combination wrenches
• Inch measurement system for use with standard American fastener specifications

Compatibility

Designed as a general-purpose inch-series hex head cap screw compatible with any 5/8-11 UNC tapped hole or standard nut.

Installation Notes

Install using a 15/16-inch wrench or socket. Ensure mating threads are clean and free of debris before engagement to avoid galling, which is common with stainless steel fasteners. Applying an anti-seize compound rated for stainless fasteners is recommended to prevent thread galling during tightening. Follow applicable mechanical or structural codes for torque requirements based on joint design.
