Value Collection 209010B Hex Cap Screw 5/8-11 X 4 in 18-8 Ss

Product Description

The VALUE COLLECTION 209010B is a hex head cap screw in a 5/8-11 thread size and 4-inch length under head, manufactured from 18-8 stainless steel. The 18-8 alloy provides solid corrosion resistance in wet, outdoor, and chemically exposed environments, making it a reliable fastener for general industrial, mechanical, and structural assemblies. The thread standard is UNC (Unified National Coarse), and the hex drive measures 15/16 inches across flats. Installers in plumbing, mechanical contracting, and equipment service regularly reach for this grade when stainless is specified by the engineer or code.

This cap screw is suited for a wide range of trade and industrial applications where corrosion resistance and dimensional consistency matter. Typical use cases include mechanical equipment mounting, pipe flange bolting, pump and blower assemblies, HVAC structural brackets, and general fastening in damp or outdoor locations. The coarse UNC thread form seats quickly and resists cross-threading during installation, which is useful in field conditions.

Key Features

• 18-8 stainless steel construction provides corrosion resistance in wet and outdoor environments
• 5/8-11 UNC thread — coarse pitch for fast engagement and field reliability
• 4-inch length under head accommodates thicker assemblies and stacked components
• 15/16-inch hex across flats — fits standard combination wrenches and sockets
• Inch measurement system with UNC thread standard for broad compatibility with inch-pattern hardware

Compatibility

Designed as a standard inch-series hex head cap screw for use with any 5/8-11 UNC tapped hole or matching nut in general mechanical and structural assemblies.

Installation Notes

Installation is performed by licensed mechanics, millwrights, plumbers, or HVAC technicians depending on the application. De-energize or depressurize the system before fastener replacement in any live mechanical or fluid assembly. Use a calibrated torque wrench when a torque specification is provided by the equipment manufacturer or applicable code. Apply an anti-seize compound if mating components are also stainless steel to prevent galling during tightening.
