Zoro Select M6 Carriage Bolts 100 Pack

These Zoro Select carriage bolts are metric Class 4.6 fasteners with a M6-1.00 thread and a 100 mm length. The pack contains 100 pieces suited for wood-to-wood or wood-to-metal joints where a smooth, rounded head is required. They conform to DIN 603 and feature a square neck that prevents rotation during tightening.

Zinc-Plated Steel Thermals and Installation

The steel bolts have a zinc-plated finish that resists corrosion in normal indoor or outdoor exposure. No moving parts or electrical load are involved, so heat, noise and power draw are not applicable. Installation uses standard M6 tooling and the right-hand coarse thread engages cleanly in matching nuts or tapped holes.

Replaces Worn or Missing M6 Fasteners

This pack replaces individual lost or corroded M6 carriage bolts in furniture, fencing or equipment assemblies. The jump is worth it when a project needs a consistent supply of 100 matching Class 4.6 bolts with 15.45 to 16.55 mm head diameter and 3.88 mm head height. Buyers who need a different diameter, length or strength grade cannot use this pack.

Questions about this item

How do I install the M6 carriage bolt so the square neck locks properly?

Drill a 6.48 mm square hole or a round hole that lets the 6.48 mm square neck seat fully; the 4.60 mm square height must sit flush in the material so the 15.45–16.55 mm round head cannot spin when you tighten the nut.

What maintenance or replacement will these Class 4.6 zinc-plated bolts need later?

Inspect the zinc finish for white rust after exposure to moisture; replace any bolt that shows red rust, thread damage, or a stretched shank because the 58 000 psi tensile strength cannot be restored once the steel yields.

What limit appears first when the joint is under sustained load?

The Class 4.6 steel yields at 58 000 psi, so the bolt will stretch permanently before the threads strip or the square neck pulls through the material.
