Value Collection A410091 Hex Head Cap Screw M12 X 1.75 Din 933

Product Description

The VALUE COLLECTION A410091 is a fully threaded metric hex head cap screw designed for fastening applications that demand corrosion resistance and structural reliability. Manufactured from Grade 316 austenitic stainless steel to the A4 material grade, this fastener meets DIN 933 standards. It features an M12 x 1.75 thread with a 45 mm length under head and a 19 mm hex drive. The Grade 316 alloy offers superior resistance to chlorides and harsh chemical environments, making it well suited for marine, plumbing, and industrial installations where carbon steel fasteners would corrode. Licensed trades and maintenance professionals working in demanding or wet environments rely on this grade for code-appropriate fastening.

This screw is appropriate for use in residential and commercial applications requiring metric fasteners with strong corrosion resistance. Typical installation scenarios include pipe flange bolting, equipment mounting in wet or coastal environments, pool and spa mechanical assemblies, and HVAC equipment brackets exposed to moisture. It is fully threaded along its shank, allowing engagement across the full 45 mm length under head. Supplied in a package quantity of 10, it suits both single-unit repair jobs and small production or service runs.

Key Features

• Grade 316 austenitic stainless steel (A4) provides strong resistance to chloride and chemical corrosion
• Fully threaded shank for maximum thread engagement across the entire 45 mm length under head
• DIN 933 standard compliance ensures dimensional consistency and interchangeability
• M12 x 1.75 metric thread size fits standard metric tapped holes and nuts
• 19 mm hex drive accommodates standard metric wrenches and sockets
• Uncoated finish maintains true stainless steel surface with no coating to chip, flake, or interfere with torque

Compatibility

Designed as an OEM-style and aftermarket replacement metric hex head cap screw for any application requiring a fully threaded M12 x 1.75 fastener conforming to DIN 933 dimensional standards.

Installation Notes

Installation requires a 19 mm wrench or socket. Stainless steel fasteners are susceptible to galling during installation — apply an appropriate anti-seize compound to the threads before torquing to reduce the risk of thread seizure. Follow applicable mechanical or structural codes for torque requirements specific to the application and joint design. Inspect mating threads for compatibility and cleanliness before assembly.
