Value Collection HC1XX05040-025BX M5 Hex Cap Screw 316 Ss

Product Description

The VALUE COLLECTION HC1XX05040-025BX is a metric hex head cap screw designed for general mechanical assembly, equipment mounting, and structural fastening applications where corrosion resistance is required. Manufactured from Grade 316 austenitic stainless steel (A4), this fastener delivers strong resistance to chlorides, acids, and marine environments compared to standard 304-grade hardware. The screw measures M5 x 0.80 thread pitch with a 40 mm length under head and features partial threading, conforming to DIN 931, EN 24014, and ISO 4014 standards. It is installed using an 8 mm hex wrench or socket and is suited for use by machinists, millwrights, plumbers, and mechanical contractors working with stainless hardware.

This fastener is used across a broad range of industries including HVAC equipment assembly, plumbing fixture mounting, pool and spa equipment, and marine or coastal installations where salt air and moisture exposure demand higher-grade corrosion-resistant hardware. The partial threading is standard for hex head bolts per DIN 931, making this screw appropriate for bolted joint applications where a grip length and bearing surface are required. The bright uncoated finish means no coating degradation over time in wet environments.

Key Features

• Grade 316 austenitic stainless steel (A4) provides superior resistance to chlorides and corrosive environments
• M5 x 0.80 metric thread with 40 mm length under head for precise metric fastening
• Partially threaded per DIN 931 standard, allowing full grip-length engagement
• 8 mm hex drive compatible with standard metric hex sockets and wrenches
• Bright uncoated finish eliminates risk of coating flaking or chemical incompatibility
• Conforms to DIN 931, EN 24014, and ISO 4014 dimensional standards

Compatibility

Designed as a standard metric hex head cap screw per DIN 931, EN 24014, and ISO 4014, suitable for any application requiring an M5 x 0.80 partially threaded hex bolt in Grade 316 stainless steel.

Installation Notes

Installation should be performed by a qualified mechanic, pipefitter, or technician familiar with metric fastener torque requirements and stainless steel galling prevention. Apply an appropriate anti-seize compound to the threads before installation, as stainless steel fasteners are prone to galling under high-torque conditions. Use a calibrated torque wrench sized for 8 mm hex drive to achieve proper clamp load without over-torquing. Follow all applicable equipment manufacturer specifications and relevant mechanical codes for the assembly being serviced.
