Value Collection HC3X18040-010BX M18 Hex Cap Screw

Product Description

The VALUE COLLECTION HC3X18040-010BX is a fully threaded hex head cap screw manufactured from 18-8 austenitic Grade A2 stainless steel with a bright, uncoated finish. It carries an M18 x 2.50 thread size with a 40 mm length under head and a 27 mm hex drive. The fastener conforms to DIN 933, EN 24017, and ISO 4017 standards, making it a reliable choice for metric fastening applications across mechanical, plumbing, HVAC, and industrial assembly work. Trades and maintenance professionals install this screw wherever corrosion resistance and metric dimensional accuracy are required.

This cap screw suits residential and commercial applications where stainless steel fasteners are specified for corrosion-prone or sanitary environments. Typical uses include equipment mounting, pipe support assemblies, HVAC bracket fabrication, pump and valve housings, and structural connections exposed to moisture or mild chemicals. Its fully threaded shank provides consistent thread engagement across the full length of the fastener, which is useful when threading into deep or blind holes.

Installation Notes

Install using a 27 mm open-end wrench, box wrench, or socket. Ensure mating threads are clean and free of debris before installation. Stainless steel fasteners are susceptible to galling under high-speed or high-torque conditions — apply an appropriate anti-seize compound and tighten slowly by hand before final torquing. Follow applicable mechanical or structural codes for the specific assembly type.
