Value Collection HC1XX18110 Hex Head Cap Screw M18

Product Description

The VALUE COLLECTION HC1XX18110 is a metric hex head cap screw designed for industrial and mechanical fastening applications requiring corrosion-resistant hardware. Manufactured from Grade 316 austenitic stainless steel (A4 designation), this screw measures M18 x 2.50 thread pitch with a 110 mm length under the head and a 27 mm hex drive. The partially threaded shank conforms to DIN 931 standards, making it a precise fit for applications where shank-to-bore contact is required for load bearing or alignment. The bright, uncoated finish leaves the base material exposed for maximum corrosion resistance without added coating variables.

This fastener is suited for use in marine, chemical processing, food service, and outdoor structural environments where chloride exposure or moisture demands a higher-grade stainless alloy over standard 18-8 or Grade 304 material. It is appropriate for use by millwrights, pipefitters, structural fabricators, and maintenance technicians working with metric-spec equipment and machinery. The DIN 931 partial-thread configuration is common in European-standard assemblies and metric machinery built to those tolerances.

Key Features

• Grade 316 austenitic stainless steel (A4) for superior chloride and corrosion resistance
• M18 x 2.50 thread pitch per metric standard
• 110 mm length under head with partially threaded shank per DIN 931
• 27 mm hex drive for standard metric wrench or socket fitment
• Bright, uncoated finish — no coating thickness to account for in tolerance-critical fits
• Sold individually — minimum order quantity of 1

Compatibility

Designed as an OEM-style replacement or direct-use metric fastener for assemblies requiring a DIN 931 hex head cap screw in M18 x 2.50 thread size with a 110 mm grip length.

Installation Notes

Installation should be performed by qualified mechanical or maintenance personnel using a calibrated torque wrench and appropriately sized 27 mm metric socket or open-end wrench. Power down or de-energize any equipment and relieve system pressure before removing or installing structural fasteners. Do not mix stainless steel fasteners with dissimilar metals in submerged or highly conductive environments without appropriate isolation to prevent galvanic corrosion. Thread engagement depth should conform to the original equipment design specification or applicable industry standards.
