Carriage Bolt M10-1.50 Class 4.6 Zinc Plated

The Zoro Select carriage bolt is a metric steel fastener with a M10-1.50 thread diameter and 25 mm length. It features a round head, square neck, and right-hand metric coarse threads. The zinc-plated finish provides corrosion resistance for general-purpose use. Each pack contains 100 pieces.

Builders needing DIN 603 compliant fasteners

This bolt suits applications requiring a square neck to prevent rotation during tightening, such as wood-to-wood or wood-to-metal connections. The Class 4.6 grade offers a tensile strength of 58,000 psi for moderate structural loads. Buyers needing higher strength grades, different lengths, or non-metric threads should look elsewhere.

M10-1.50 thread with 25 mm length and 100 pack

The thread specification M10-1.50 combined with a 25 mm fastener length determines fit for pre-drilled holes and mating nuts. The square neck width of 10.58 mm and height of 6.60 mm must match the receiving material slot. Verify these dimensions against your design requirements before ordering.

Questions about this item

Will the Class 4.6 steel stretch or yield first under sustained heavy load?

The bolt is rated to a tensile strength of 58,000 psi, so that is the limit reached before permanent deformation begins.

Does the zinc-plated finish resist heat or corrosion during all-day outdoor exposure?

The zinc plating provides corrosion resistance for outdoor use, and the steel material handles normal ambient temperatures without degradation.

What size nut and washer must I already have to install these M10 bolts?

You need M10-1.50 metric coarse nuts and washers that match a 23.35 to 24.65 mm head diameter and 10.58 mm square neck width.
