Class 10.9 Hex Head Cap Screws
When a joint keeps loosening or stretching, step up to Class 10.9 hex head cap screws for Grade 8 equivalent muscle and hard clamp load. Choose coarse thread for general MRO builds, fine thread for better hold in vibration. Zinc or oil-dipped finishes cut friction and fight corrosion. Stock singles or assortments to keep uptime high.
