Value Collection HC1XX18100-001BX M18 Hex Cap Screw

Product Description

The VALUE COLLECTION HC1XX18100-001BX is a metric hex head cap screw engineered for demanding fastening applications where corrosion resistance is critical. Manufactured from Grade 316 Austenitic Grade A4 stainless steel with a bright uncoated finish, this partially threaded fastener meets DIN 931 standards. It features an M18 x 2.50 thread size with a 100 mm length under head and a 27 mm hex drive. Machinists, millwrights, pipefitters, and industrial maintenance technicians install this type of fastener in assemblies requiring reliable clamping force and long-term resistance to oxidation and chemical exposure.

This hex head cap screw is suited for use in marine, chemical processing, food service, and other corrosive environments where standard carbon steel fasteners would degrade prematurely. The partially threaded shank provides a bearing surface that helps maintain alignment in bolted joints. It is appropriate for both structural and mechanical assemblies where metric fastener standards are specified.

Key Features

• Grade 316 Austenitic Grade A4 stainless steel construction for superior corrosion resistance
• Meets DIN 931 standard for partially threaded metric hex head cap screws
• M18 x 2.50 thread size with 100 mm length under head
• 27 mm hex drive size for standard wrenching
• Bright uncoated finish — no coating to chip, flake, or interfere with dimensional tolerances
• Partially threaded shank provides an unthreaded grip length for precise joint alignment

Compatibility

Designed as a DIN 931 compliant metric hex head cap screw suitable for M18 x 2.50 threaded assemblies requiring Grade 316 stainless steel fasteners.

Installation Notes

Installation should be performed by a qualified mechanic or industrial maintenance technician familiar with metric fastener standards. Always verify that the mating nut or tapped hole conforms to M18 x 2.50 thread specification before assembly. Use an appropriate 27 mm open-end, box, or socket wrench to drive the fastener; do not use an impact tool without confirming the application allows impact-rated torque. Follow applicable industry or equipment manufacturer torque guidelines for Grade A4 stainless fasteners to avoid galling, which is a known risk with stainless steel threaded components.
