Zoro Select M6 Carriage Bolts 50 Pack

This pack supplies fifty metric carriage bolts with an M6-1.00 thread and a 60 mm length. The A2 stainless steel construction provides corrosion resistance for indoor and outdoor assemblies. The square neck locks into wood or metal to prevent the bolt from turning while a nut is tightened. Builders and maintenance crews use these for timber framing, fencing and general structural fastening.

Square Neck and Plain Finish

The square neck measures 6.48 mm wide by 4.60 mm high and engages the workpiece so a single spanner can tighten the joint. A plain finish leaves the stainless surface uncoated, avoiding galvanic issues when mixed with other stainless components. DIN 603 dimensional tolerances give a head diameter between 15.45 mm and 16.55 mm and a head height of 3.88 mm for consistent clamp load. Right-hand metric coarse threads simplify sourcing matching nuts and washers.

Metric Coarse Thread Limits

The M6-1.00 coarse pitch suits general-purpose fastening but is not intended for high-vibration or precision adjustment applications. Tensile strength is rated at 101,500 psi, which limits the bolt to light and medium structural loads. A2 grade stainless steel resists atmospheric corrosion but is not rated for marine immersion or sustained contact with chlorides. Buyers requiring higher strength grades or finer thread pitches must select different fasteners.

Questions about this item

Will the A2 stainless steel bolts need replacement due to corrosion in outdoor use?

A2 stainless steel resists general corrosion but can pit in chloride-rich environments such as coastal or de-iced areas; inspect periodically and replace any bolts showing pitting or loss of cross-section.

What load limit governs the M6-1.00 coarse thread under sustained tension?

The bolts are rated to a tensile strength of 101,500 psi; the coarse thread and 60 mm length determine the engaged thread area that carries the sustained load.

Does the plain finish affect heat dissipation or noise when the bolts are under constant vibration?

The plain finish adds no insulating coating; heat dissipation and any vibration noise depend on the joint design and clamping force rather than the bolt surface itself.
