Manufactured under strict quality controls, this M7 x 97mm hex head cap screw is forged from premium brass alloy, providing exceptional resistance to corrosion and tarnishing, crucial for applications exposed to moisture or chemicals. The nominal M7 thread pitch ensures compatibility with standard metric fixtures, while the generous 97mm length facilitates assembly in thicker materials. Its substantial 33mm hex head width enables secure tightening with standard wrenches or socket drivers, distributing load effectively to prevent over-stressing of the mating components. The inherent conductivity of brass also makes it suitable for electrical grounding applications.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Select the appropriate wrench or socket for the 33mm hex head. 2. Align the M7 thread of the cap screw with the pre-tapped hole or nut. 3. Tighten the screw with consistent torque, avoiding over-tightening to prevent thread stripping or material deformation.
