Detailed Engineering Specifications

Specified by design engineers worldwide, this M12x50mm brass hex head cap screw features a nominal diameter of M12 and a shank length of 50mm. The robust hexagonal head provides a 22mm width for optimal torque application with standard tools. Crafted from high-grade brass, it exhibits exceptional resistance to corrosion, particularly in moist or saline atmospheres, and is inherently non-magnetic, which is critical for electrical and electronic assemblies. Its malleability also allows for slight deformation without fracturing, ensuring a secure joint under moderate stress.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using excessive force, leading to thread stripping or bolt breakage.Always use a calibrated torque wrench and adhere to manufacturer-recommended torque specifications.
Using the wrong tool size, which can damage the hex head and lead to an incomplete fit.Confirm the correct wrench or socket size (22mm for this product) is used before applying torque.

Common Applications

  • Electrical enclosures and connectors
  • Marine hardware and fittings
  • Corrosive environment assemblies
  • Decorative and architectural components

⚠️ Engineering Warnings

  • Brass is a softer material than steel; avoid over-torquing to prevent thread damage or stripping.
  • Not recommended for high-tensile strength or structural load-bearing applications where steel fasteners would be more suitable.
