Carriage Bolt M10-1.50 100 mm Class 4.6

These zinc-plated steel carriage bolts feature a round head and square neck that locks into wood or metal to prevent rotation during tightening. The metric coarse thread M10-1.50 and 100 mm length suit structural joints in framing, furniture and equipment assembly. Pack of 50 pieces.

DIN 603 specification and Class 4.6 strength

Manufactured to DIN 603 with a tensile strength of 58,000 psi, the Class 4.6 grade provides reliable clamping force for general-purpose fastening. The zinc plating resists corrosion in indoor and sheltered outdoor environments. Right-hand threads ensure standard tool compatibility.

Square neck and round head dimensions

The square neck measures 10.58 mm wide by 6.60 mm high, fitting standard square holes to stop the bolt from spinning. Head diameter ranges from 23.35 to 24.65 mm with a height of 5.38 mm, giving a broad bearing surface. Not intended for high-stress critical connections requiring higher property classes.

Questions about this item

How do I install the M10-1.50 carriage bolt so the square neck locks properly?

Drill a 10 mm clearance hole, insert the bolt through the parts, and tap the 10.58 mm square neck into the mating slot until the 23.35 to 24.65 mm round head seats flush; the 6.60 mm square height prevents rotation while you tighten the nut.

What maintenance or replacement will the zinc-plated Class 4.6 bolts need over time?

Inspect the zinc finish for white rust; if corrosion reaches the base steel or the 58,000 psi tensile strength is compromised by stretching, replace the affected bolts from the 50-piece pack.

Which limit appears first when the M10-1.50 bolt is under sustained load?

The Class 4.6 steel yields at its 58,000 psi tensile strength before the coarse threads strip or the 10.58 mm square neck shears, so permanent stretch is the first failure mode.
