Value Collection HC1XX05045-050BX M5 Hex Cap Screw 316 Ss

Product Description

The VALUE COLLECTION HC1XX05045-050BX is a metric hex head cap screw engineered for industrial and trade applications requiring corrosion resistance. Manufactured from Grade 316 austenitic stainless steel (A4 grade per DIN 931 classification), this fastener offers strong resistance to chlorides and oxidizing environments. The screw features an M5 x 0.80 thread profile with a 45 mm length under head and is partially threaded, conforming to DIN 931 standards. The bright, uncoated finish maintains dimensional accuracy and is suitable for use in wet, marine, chemical, or food-service-adjacent environments where carbon steel fasteners would be unsuitable. Installed by maintenance technicians, millwrights, and mechanical contractors.

This fastener is well-suited for light-duty mechanical assemblies, equipment enclosures, brackets, and structural connections in corrosive or high-moisture environments. Typical applications include HVAC equipment mounting, plumbing fixture hardware, pool and spa equipment assemblies, and marine or coastal installations. The M5 thread size and 45 mm shank length make it appropriate for medium-gauge panel and frame connections where partial threading is required to bear load against an unthreaded shank section.

Key Features

• Grade 316 austenitic stainless steel (A4) provides elevated corrosion resistance, including resistance to chloride-bearing environments
• Partially threaded per DIN 931, allowing shank bearing load in through-bolt applications
• M5 x 0.80 metric thread profile for precise metric fastening applications
• 8 mm hex drive size compatible with standard metric wrenches and sockets
• Bright, uncoated finish maintains tight tolerances without added coating thickness
• Sold in minimum order quantities of 50 units, suitable for production and service stock

Compatibility

Designed as a DIN 931 partially threaded hex head cap screw for use in standard M5 x 0.80 metric threaded applications across HVAC, plumbing, pool, and general mechanical assemblies requiring Grade 316 stainless steel fasteners.

Installation Notes

Installation requires a standard 8 mm hex wrench or socket. Ensure mating threads are clean and free of debris before installation. Stainless steel fasteners are susceptible to galling — apply an appropriate anti-seize compound when torquing into stainless or aluminum threads. Follow applicable equipment manufacturer torque specifications and relevant mechanical codes for the assembly type.
