Value Collection R80826824 Hex Head Cap Screw 5/8-18

Product Description

The VALUE COLLECTION R80826824 is a 5/8-18 hex head cap screw measuring 3 inches under the head, manufactured from 18-8 stainless steel with no coating applied. The partially threaded shank allows for proper clamping force in bolted joints where thread engagement in a tapped hole or nut is required. The UNF (Unified National Fine) thread pitch of 18 threads per inch provides tighter thread engagement and improved resistance to loosening under vibration compared to coarse-thread equivalents. This fastener is suited for mechanical, plumbing, HVAC, and general trade assembly applications where corrosion resistance is a primary requirement.

This hex head cap screw is used across a range of trade and industrial installations including HVAC equipment mounting, plumbing fixture assembly, electrical enclosure fabrication, and structural component fastening in corrosive or outdoor environments. The 18-8 stainless steel construction makes it appropriate for applications exposed to moisture, mild chemicals, or coastal conditions. Licensed trades and maintenance professionals install this fastener with standard hex tooling wherever a fine-thread, stainless, partially threaded cap screw is specified.

Key Features

• 5/8-18 UNF fine thread for reliable engagement and vibration resistance
• 3-inch length under head with partial threading for proper clamping in bolted joints
• 18-8 stainless steel construction provides corrosion resistance in wet and outdoor environments
• Uncoated finish maintains base material properties without added plating
• Hex drive head accepts standard hex wrenches and sockets

Compatibility

Designed as a standard 5/8-18 UNF hex head cap screw suitable for use wherever a partially threaded, 18-8 stainless steel fastener of this thread size and length is specified.

Installation Notes

Install using a properly sized hex wrench or socket driver rated for the fastener size. Power down or de-energize any equipment before fastening components in electrical or HVAC assemblies. Do not mix stainless steel fasteners with dissimilar metals in applications where galvanic corrosion is a concern. Follow applicable mechanical codes and equipment manufacturer torque guidelines for the assembly being serviced.
