Value Collection 3MAHC0120055CP M12 Hex Cap Screw Din 933

Product Description

The VALUE COLLECTION 3MAHC0120055CP is a metric hex head cap screw manufactured from 18-8 austenitic stainless steel, Grade A2, with no additional coating applied. The fastener carries an M12 x 1.75 thread and measures 55 mm under the head with full threading along the entire shank. Driven by a 19 mm hex, it meets the DIN 933 standard for fully threaded hex bolts. This screw is a practical choice for maintenance, mechanical assembly, and fabrication work where corrosion resistance is required without plating or surface treatment.

This fastener is suited for general mechanical assembly, structural bracketing, and equipment maintenance in environments where stainless steel is preferred over zinc-plated or carbon steel hardware. Typical applications include HVAC equipment mounting, pump and compressor assembly, plumbing fixture installation, and outdoor or corrosive-environment installations. Trade professionals including HVAC technicians, plumbers, and pipefitters commonly use M12 fasteners in these contexts. Sold individually per piece; minimum order quantity is 25 units.

Key Features

• 18-8 austenitic stainless steel, Grade A2 — provides corrosion resistance in wet and outdoor environments
• Fully threaded shank along the entire 55 mm length under head
• M12 x 1.75 metric thread profile per DIN 933 standard
• 19 mm hex drive — fits standard metric wrenches and sockets
• Uncoated finish — no plating that can chip, flake, or introduce galvanic incompatibility with stainless hardware

Compatibility

Designed as a DIN 933 fully threaded metric hex cap screw for M12 x 1.75 threaded applications in mechanical, HVAC, plumbing, and general industrial assemblies.

Installation Notes

Installation should be performed by qualified tradespeople using a properly sized 19 mm wrench or socket. Stainless steel fasteners are susceptible to galling — apply an anti-seize compound to the threads before installation to reduce friction and prevent thread damage. Power down or de-energize any equipment before accessing fastened assemblies. Avoid mixing stainless hardware with dissimilar metals in highly conductive or corrosive environments where galvanic corrosion could be a concern.
