Value Collection A997220 Hex Cap Screw 5/8-11 X 3-1/4 in 18-8 Ss

Product Description

The VALUE COLLECTION A997220 is a partially threaded hex head cap screw in 5/8-11 UNC thread size with a 3-1/4 inch length under head. Manufactured from 18-8 stainless steel with no coating applied, this fastener delivers corrosion resistance suitable for demanding service environments. The hex drive head accepts standard wrenches and sockets for reliable torque application. This screw is sold in a package quantity of 10 and is well suited for mechanical assembly, equipment mounting, and structural connection work across trade and industrial applications.

This fastener is appropriate for use in HVAC equipment assembly, plumbing fixture mounting, electrical enclosure fabrication, and general mechanical installations where stainless steel corrosion resistance is required. The UNC thread form is the standard for inch-system fastener applications in North America. Partial threading on the shank provides a smooth bearing surface for applications requiring precise clamping or alignment. Licensed tradespeople and maintenance technicians working on corrosive or outdoor-exposed equipment will find this screw a practical choice.

• 3-1/4 inch length under head for deep engagement applications
• 18-8 stainless steel construction for corrosion resistance
• Partially threaded shank provides smooth bearing surface between fastener and mating material
• Uncoated finish — no plating or treatment that could affect dimensional tolerances
• Sold in a package of 10 with a minimum order quantity of 1

Compatibility

Designed as a standard inch-system UNC hex head cap screw compatible with any application specifying a 5/8-11 x 3-1/4 inch partially threaded hex fastener in 18-8 stainless steel.

Installation Notes

Install using an appropriate hex wrench or socket sized for the fastener head. Confirm that the mating tapped hole or nut meets the 5/8-11 UNC thread specification before installation. Stainless steel fasteners are susceptible to galling — apply an anti-seize compound to the threads when tightening into stainless or aluminum mating parts to prevent thread seizure. Follow applicable codes and equipment manufacturer torque requirements for the specific assembly.
