Value Collection HC1XX18080-001BX M18 Hex Cap Screw

Product Description

The VALUE COLLECTION HC1XX18080-001BX is a metric hex head cap screw designed for industrial and mechanical fastening applications requiring corrosion resistance and structural reliability. Manufactured from Grade 316 austenitic stainless steel (A4 grade), this screw offers strong resistance to chlorides, acids, and marine environments. It features an M18 x 2.50 thread size with an 80 mm length under head, a 27 mm hex drive, and is partially threaded per DIN 931 standards. The bright, uncoated finish maintains dimensional accuracy and is suited for environments where surface treatments could interfere with fit or chemical compatibility. Mechanical contractors, marine fabricators, and industrial maintenance technicians are the typical installers.

This hex head cap screw is intended for metric fastening applications in industrial equipment, structural assemblies, process piping supports, and marine or coastal installations where stainless steel is specified for corrosion protection. The DIN 931 partial-thread configuration makes it appropriate for through-bolting applications where thread engagement is limited to the nut or tapped hole rather than the full grip length. It is sold individually and ordered in single-unit multiples.

Key Features

• Grade 316 austenitic stainless steel (A4) provides strong resistance to corrosion, including chloride and marine environments
• M18 x 2.50 metric thread, partially threaded per DIN 931 standard
• 80 mm length under head for through-bolt and structural fastening applications
• 27 mm hex drive for standard metric wrench or socket engagement
• Bright, uncoated finish preserves close dimensional tolerances

Compatibility

Designed as a DIN 931 metric hex head cap screw for use with M18 x 2.50 metric nuts, washers, and tapped components in standard metric fastening assemblies.

Installation Notes

Installation should be performed by qualified mechanical or industrial technicians using a properly sized 27 mm metric wrench or socket. De-energize and depressurize any system before replacing structural fasteners. Avoid mixing stainless steel hardware with dissimilar metals in contact without appropriate isolation to prevent galvanic corrosion. Apply a compatible anti-seize compound when fastening into stainless or aluminum mating surfaces to prevent galling during assembly or future removal.
