Zoro Select Carriage Bolt M6-1.00×50 mm A2 Stainless Steel PK50

Carriage bolts for metric assemblies

This pack contains fifty M6 carriage bolts with a 1.00 mm coarse thread pitch and 50 mm length. The square neck locks into a matching hole to prevent rotation while a nut is tightened. A2 stainless steel provides general corrosion resistance for indoor and outdoor fixtures. Builders assembling timber frames, metal brackets or trailer decks will find the quantity convenient.

Fits M6 hardware and frees installation time

Each bolt requires a standard M6 nut and an optional washer; the 15.45 to 16.55 mm round head seats flush without a separate washer face. The 6.48 mm square neck drops into pre-punched or drilled square holes, eliminating the need to hold the bolt head during tightening. DIN 603 dimensions ensure interchangeability with other metric carriage bolts in the same size class.

Holds clamp load under prolonged tension

The A2 grade delivers a tensile strength of 101, 500 psi, so the fastener resists stretching when joints are subjected to sustained vibration or seasonal wood movement. Right-hand metric coarse threads maintain engagement over long clamping distances. Plain finish avoids hydrogen embrittlement risks that can affect plated alternatives in critical structural connections.
