M12 A2 Stainless Socket Cap Bolt With Shank

Product Description

M12 × 50mm A2 Stainless Steel Socket Cap Bolts With Shank

M12 × 50mm socket head cap bolts manufactured from corrosion-resistant A2 stainless steel. These part-threaded fasteners have an internal hexagon drive and an unthreaded shank, making them suitable for machinery, equipment and general engineering assemblies.

• Thread size: M12 × 1.75
• Overall length: 50mm
• Thread type: Standard metric coarse
• Material: A2 stainless steel
• Head style: Cylindrical socket head
• Drive: Internal hexagon
• Nominal hex key size: 10mm
• Nominal head diameter: Approximately 18mm maximum
• Nominal head height: 12mm
• Listed thread length: 36mm
• Approximate shank length: 14mm
• Dimensional pattern: DIN 912 / ISO 4762

This bolt has a standard M12 × 1.75 coarse thread and must be used with a matching M12 × 1.75 nut or tapped hole. It is not compatible with M12 × 1.5 or M12 × 1.25 fine-pitch threads.

The shank length is calculated by subtracting the listed 36mm thread length from the 50mm nominal overall length. Confirm critical dimensions before specifying this bolt for a precision assembly.

A2 Stainless Steel

A2 stainless steel provides good corrosion resistance for many indoor, outdoor and general engineering applications. For marine environments or regular exposure to salt and chlorides, A4 stainless steel will usually provide better corrosion resistance.

A2 identifies the stainless-steel material group. It does not by itself state a mechanical property class such as A2-70 or A2-80.

Preventing Thread Galling

Stainless steel threads can gall or seize during installation. Clean mating threads, suitable anti-seize lubricant, controlled installation speed and avoiding excessive tightening can help reduce this risk.
