Detailed Engineering Specifications

Engineered for reliability and performance, these M12 x 113mm hex head cap screws are manufactured from high-grade brass (CuZn alloys), providing excellent tensile strength and resistance to galvanic corrosion. The 17mm hex head ensures secure torque application with standard tooling. Their non-magnetic nature makes them suitable for applications sensitive to magnetic fields, such as electrical installations and marine hardware where saltwater exposure is prevalent. The inherent malleability of brass also allows for some deformation under load without catastrophic failure, contributing to joint integrity in vibration-prone environments.

Installation Procedure

1. Select the appropriate tool (e.g., socket wrench or adjustable wrench) for the 17mm hex head. 2. Ensure the mating threads are clean and free from debris. 3. Thread the cap screw into the receiving hole by hand for the first few turns to prevent cross-threading. 4. Tighten the cap screw to the recommended torque specification for M12 brass fasteners, taking care not to overtighten, which could damage the threads or the brass material.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using excessive force, leading to stripped threads or fastener breakage.Employ a torque wrench and adhere to manufacturer-specified torque values for M12 brass fasteners.
Using incompatible tools that damage the hex head.Utilize properly sized sockets or wrenches designed for hex heads.
Cross-threading the fastener due to improper initial engagement.Always start threading by hand to ensure proper alignment before applying tool torque.

Common Applications

  • Marine hardware and fittings
  • Electrical connectors and enclosures
  • Architectural elements
  • Corrosion-sensitive assemblies

⚠️ Engineering Warnings

  • Brass is a softer material than steel; avoid over-torquing.
  • While corrosion-resistant, brass can be susceptible to dezincification in certain aggressive chemical environments. Consult material compatibility charts if unsure.
