M8 x 100mm Coach Bolts - BZP Grade 4.8 - DIN 603 - Pack of 4
DIN 603 coach bolts (also known as carriage bolts or cup square bolts) feature a distinctive domed mushroom head with a square shank section beneath. The square section bites into the material on tightening, preventing the bolt from rotating — no need to hold the head during installation.
Each pack includes matching full nuts and Form A washers for a complete fixing solution straight out of the box.
