Value Collection HC3XX04020-050BX M4 Hex Cap Screw 316 Ss Din 933

Product Description

The VALUE COLLECTION HC3XX04020-050BX is a metric hex head cap screw intended for industrial, mechanical, and trade assembly applications requiring corrosion resistance. Manufactured from Grade 316 austenitic stainless steel to the A4 material designation, this fastener resists chloride-rich and marine environments where standard stainless grades fall short. The screw measures M4 x 0.70 thread pitch with a 20 mm length under the head and is fully threaded along its shank. It conforms to DIN 933 dimensional standards and is supplied with a bright, uncoated finish. Licensed tradespeople, millwrights, marine service technicians, and HVAC equipment installers use this fastener when stainless hardware is specified by code or engineering requirement.

This fastener suits metric-threaded assemblies in residential and commercial equipment, pool and spa hardware, marine enclosures, plumbing panel supports, and any installation where prolonged moisture or chemical exposure demands a higher-grade stainless alloy. The M4 x 0.70 thread pitch is commonly found in equipment covers, mounting brackets, and control enclosures across HVAC, electrical, and pool service trades. Sold in a minimum order quantity of 50 pieces per box, making it practical for service vans and shop stock where consistent hardware supply is required.

Compatibility

Designed for use in any application requiring a fully threaded M4 x 0.70 metric hex head cap screw conforming to DIN 933. Suitable for metric-threaded assemblies in HVAC equipment, plumbing panels, electrical enclosures, and pool and spa hardware where Grade 316 stainless steel is specified.

Installation Notes

Installation is performed by any qualified trade technician working with metric fastener assemblies. Always de-energize electrical equipment and shut off fluid systems before servicing any assembly that requires fastener removal or replacement. Use a calibrated torque wrench and consult the equipment manufacturer's fastener torque specifications for the assembly being serviced. Do not mix stainless steel fasteners with dissimilar metals in environments where galvanic corrosion is a concern.
