Manufactured from Class 8.8 steel, this M18 x 2.5mm hex cap screw provides dependable clamping force for mid-range structural and heavy equipment applications. Class 8.8 delivers approximately 800 MPa tensile strength and serves as the metric equivalent to SAE Grade 5, meeting the load requirements of most industrial, automotive, agricultural, and construction joints without the premium cost of Class 10.9 or 12.9 grades. The hex head accepts standard wrenches and sockets for efficient installation and consistent torque application. A zinc plated finish provides RoHS compliant corrosion protection that extends service life in indoor and sheltered outdoor environments while maintaining a uniform, professional appearance.
A Hex Bolt is measured as: Diameter - Thread Pitch x Length from Under Head
FT = Full Thread
PT = Partial Thread
