Zoro Select Carriage Bolt M10-1.50 x 55 mm Class 4.6 PK50

Carriage Bolt M10-1.50 x 55 mm

The Zoro Select carriage bolt uses a metric coarse thread of M10-1.50 and measures 55 mm in length. A square neck under the round head locks into wood or metal to prevent rotation during tightening. Class 4.6 steel provides a tensile strength of 58,000 psi for general-purpose fastening. Supplied in a pack of 50 pieces.

Zinc-plated steel with DIN 603 dimensions

The fastener is made from basic steel with a zinc-plated finish for corrosion resistance. Head diameter ranges from 23.35 to 24.65 mm with a height of 5.38 mm. The square neck measures 10.58 mm wide by 6.60 mm high, matching DIN 603 standards. Right-hand threads accept standard metric nuts and washers.

Class 4.6 strength limits structural use

The 58,000 psi tensile rating suits non-critical joints but does not meet high-strength structural requirements. Metric coarse threads at 1.50 mm pitch limit fine-adjustment applications. The fixed 55 mm length and M10 diameter cannot be altered for other grip ranges. Buyers needing higher grades or different diameters must select alternative fasteners.
