Bolts used for tightening timing belt pulleys-dampers and FEAD (Front Engine Accessory Drive) accessory components. May be individual bolts ranging from M12-M16, or multiple smaller bolts, usually 4-6 to M8-M10. Must be able to guarantee a precise axial load since their purpose is to keep the pulley properly timed with the crankshaft on which the phonic wheel is also mounted. They have a 10.9, 12.9 strength rating with the possibility of being developed to higher specific ratings. They work in the plastic range and are tightened based on torque plus rotation, they rarely have a thread lock and the individual bolts have large washers sometimes with specific shapes to ensure the best contact with the pulley.

Main menu Company Products Customers & Suppliers Organization Press Contacts Careers User menu Languages CRITICAL FASTENERS Hexagon Socket Head Bolts The bolt that has made us famous in Italy first and then in the World. Type of bolt with a compact cylindrical head and hexagon socket, may be combined with a shank formed by a helical spiral which works by distributing loads on the shank itself, thus increasing elasticity. Easy to drive thanks to the good grip offered by its specific key, ensures improved and easier assembly. Its peculiarity is to be able to transmit considerable torque, higher than bolts with a flat blade or Phillips driver, occupying less space. Primarily used in assemblies where compactness and tightening precision are required.
