Detailed Engineering Specifications

Specified by design engineers worldwide, this M5x47mm hex head cap screw is manufactured from high-grade carbon steel, offering excellent tensile strength and a reliable shear resistance. The M5 thread size ensures precise engagement with corresponding nuts and tapped holes, while the 47mm length accommodates moderate material thicknesses. The 7mm head width provides a substantial bearing surface for standard hex wrenches, facilitating secure tightening and preventing cam-out. This configuration is ideal for applications requiring consistent performance under moderate to high stress.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using an improperly sized hex wrench, leading to cam-out and potential damage to the screw head.Always use a hex wrench that precisely fits the 7mm head width to ensure full engagement and prevent stripping.
Over-tightening the screw beyond its tensile strength, which can lead to thread damage or screw failure.Adhere to recommended torque specifications for M5 carbon steel screws to avoid overstressing the fastener.

Common Applications
