Value Collection HC3XX12045-025BX M12 Hex Cap Screw 316 Ss

Product Description

The VALUE COLLECTION HC3XX12045-025BX is a fully threaded hex head cap screw manufactured to DIN 933 standards in Grade 316 austenitic stainless steel (A4). With a thread size of M12 x 1.75 and a length under head of 45 mm, this fastener is built for metric-standard bolted connections where corrosion resistance is a primary concern. The 316 stainless alloy provides superior resistance to chlorides and acidic environments compared to standard 304 grade, making it well suited for demanding service conditions. A 19 mm hex drive allows standard wrenching with common metric tooling.

This screw is used in mechanical, structural, and industrial assembly applications where metric fasteners and corrosion-resistant materials are required. Typical installations include marine hardware, food-processing equipment, chemical handling systems, pool and waterpark infrastructure, and coastal HVAC or plumbing support structures. The fully threaded body makes it appropriate for through-bolting applications or use with threaded inserts across the full shank length. Trade professionals in plumbing, electrical, HVAC, and general mechanical trades regularly specify A4-grade fasteners for outdoor and wet-environment installations.

Key Features

• Grade 316 austenitic stainless steel (A4) for excellent corrosion resistance in chloride and marine environments
• Fully threaded shank per DIN 933 — usable across the entire bolt length
• M12 x 1.75 metric thread pitch for compatibility with standard metric nuts and tapped holes
• 19 mm hex head for use with standard metric wrenches and sockets
• Bright uncoated finish — no plating to flake, pit, or galvanically react with stainless hardware
• Minimum order quantity of 5 units ensures job-site supply without overstocking

Compatibility

Designed for use in any metric bolted connection requiring an M12 x 1.75 fully threaded hex head cap screw conforming to DIN 933. Mates with standard M12 x 1.75 metric nuts, washers, and tapped components.

Installation Notes

Installation should be performed by a qualified mechanic or tradesperson using calibrated metric tooling appropriate to the joint design. Always apply the correct fastener torque for the joint material and load requirements as specified by the equipment manufacturer or applicable structural standards — no torque value is provided with this fastener. Avoid mixing stainless fasteners with carbon steel hardware in the same joint to prevent galvanic corrosion. Do not use power impact tools without a torque-limiting setting, as over-torquing stainless fasteners can cause galling of the threads.
