Zoro Select M08250.100.0030 Carriage Bolt M10-1.50 30 mm Class 4.6 PK100

Zoro Select M10 Carriage Bolts

These Zoro Select carriage bolts come in a pack of 100 pieces with an M10 by 1.50 metric coarse thread and a 30 mm fastener length. They are manufactured to DIN 603 standards from Class 4.6 steel with a zinc-plated finish for corrosion resistance. The round head measures between 23.35 and 24.65 mm in diameter with a 5.38 mm height. A square neck of 10.58 mm width and 6.60 mm height prevents rotation during tightening.

Suited for metal-to-wood joints needing a smooth

The square neck locks into wood or soft metal so the bolt will not spin when the nut is tightened, making these ideal for timber construction, fencing and trailer beds where a flush, rounded head is preferred. Builders who require a higher tensile rating than the 58,000 psi Class 4.6 rating provides should select a stronger grade. Projects demanding stainless steel or hot-dip galvanised corrosion protection will need a different fastener finish.

Consistent clamping under sustained load

Class 4.6 steel yields predictably under continuous tension, so clamping force remains stable in structural assemblies such as deck frames or machinery bases where vibration occurs. The zinc plating resists surface oxidation that could accelerate thread wear over long service periods. The right-hand metric coarse thread allows straightforward disassembly for maintenance without special tools.
