Value Collection HC3XX08016-050BX M8 Hex Cap Screw 316 Ss

Product Description

The VALUE COLLECTION HC3XX08016-050BX is a fully threaded hex head cap screw sized M8 x 1.25 with a 16 mm length under head, manufactured from Grade 316 austenitic stainless steel classified as Grade A4. The 316 alloy provides strong resistance to chloride corrosion and oxidation, making this fastener well-suited for wet, marine, or chemically exposed environments. It features a 13 mm hex drive and conforms to DIN 933 dimensional standards. Machinists, millwrights, maintenance technicians, and plumbing and HVAC installers working with stainless hardware will find this screw appropriate for structural and mechanical assembly applications.

This fastener is used in metric fastening applications across light industrial, commercial, and mechanical assembly contexts. It is a common choice where corrosion resistance is required, such as pool equipment mounting, marine hardware, food processing equipment, and outdoor HVAC or plumbing installations. Its fully threaded shank allows engagement along the entire length in through-hole or shallow-depth applications. The DIN 933 standard ensures dimensional interchangeability with metric hardware sourced from other compliant manufacturers.

Key Features

• M8 x 1.25 metric thread with 16 mm length under head for precise fitment in metric assemblies
• Fully threaded shank per DIN 933 for maximum thread engagement across the full fastener length
• Grade 316 austenitic stainless steel (Grade A4) for superior chloride and corrosion resistance
• 13 mm hex drive compatible with standard metric wrenches and sockets
• Bright uncoated finish maintains dimensional accuracy and avoids coating-related tolerance buildup

Compatibility

Designed for use in metric fastening applications requiring DIN 933-compliant M8 x 1.25 hex head cap screws. Dimensionally interchangeable with other DIN 933 M8 fasteners in metric-threaded assemblies.

Installation Notes

Install using a 13 mm wrench or socket driver. Confirm the mating thread is M8 x 1.25 metric before installation to avoid cross-threading. When installing stainless steel fasteners into stainless threaded holes, apply an anti-seize compound to prevent galling. Follow applicable mechanical or structural codes for the specific application, and do not exceed the rated load for the fastener grade.
