Zoro Select M8 Carriage Bolt Pack
This pack contains 50 stainless steel carriage bolts with M8-1.25 metric coarse threads and a 35 mm shank length. They meet DIN 603 dimensions and are made from A2 grade material with a plain finish. The square neck prevents rotation during tightening in wood or metal. Right-hand threads suit standard tools.
DIN 603 Standard And Metric Coarse Thread
The bolts follow DIN 603 for head and square-neck dimensions with a thread pitch of 1.25 mm. Tensile strength is rated at 101,500 psi for structural calculations. Metric coarse threads require matching M8 nuts and tapped holes. A2 stainless steel resists corrosion but is not rated for marine or high-chloride environments.
Square Neck And Round Head For Everyday Use
The 19.35 to 20.65 mm round head distributes load without a washer in many applications. Square neck height of 5.60 mm and width of 8.58 mm lock into pre-drilled square holes or soft material. Head height of 4.88 mm keeps the profile low. Pack of 50 suits repeat jobs or small production runs.

Questions about this item
Should I choose the M8-1.25 x 35 mm pack of 50 or a different length?
The M8-1.25 x 35 mm pack of 50 suits joints needing a 35 mm shank; select a longer bolt only if the clamped material exceeds that grip length.
What does the 101,500 psi tensile strength mean when the bolt is installed?
It means the A2 stainless shank can withstand roughly 101,500 psi before permanent stretch, so the joint stays secure under high clamping loads.
Does the DIN 603 square neck limit the hole size I can use?
Yes, the 8.58 mm square width requires a hole no larger than that, otherwise the neck will spin instead of locking the bolt during tightening.
