Excellent quality for industrial use
These bolts meet the exact specifications needed for our assembly line. The zinc plating looks consistent and the threading is clean.

True Grade 12.9
We tested the hardness and it checks out. Critical for our high-stress applications. Very satisfied with the consistency.

Good value bulk pack
Solid bolts for the price. One box had a minor dent but the contents were unaffected. Would order again.

Packaging could be better
The bolts themselves are fine, but they were loose in the box. Some minor surface scratches on arrival.
Q: Is a material certificate available?
A: Yes, mill certificates can be provided upon request for bulk orders. Please contact us before purchasing.
Q: Are these suitable for outdoor use?
A: The zinc plating offers moderate corrosion resistance. For harsh outdoor environments, we recommend additional coating or stainless steel alternatives.
Q: What is the thread pitch for M8?
A: The standard coarse thread pitch for M8 DIN 933 bolts is 1.25mm.
Q: What is the recommended torque for the M10 size?
A: Torque values depend on lubrication and application. Please refer to standard DIN torque tables for Grade 12.9 M10 bolts.
Q: Do these come with matching nuts?
A: This listing is for bolts only. We recommend using Grade 12 or higher nuts for proper clamping force.
