Detailed Engineering Specifications

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.
