Perfect for automotive use
Used these on my car engine mount. They held up well under vibration and heat. Highly recommend.

Excellent quality bolts
These screws fit perfectly in my project. The zinc plating looks uniform and the heads did not strip under torque.

Precise threading
Threads are clean and cut precisely. No issues screwing them into tapped holes. Will buy again.

Good but packaging damaged
The bolts themselves are high quality grade 8.8. However, the plastic box arrived cracked. Product inside was fine.
Q: What is the tensile strength?
A: Grade 8.8 indicates a minimum tensile strength of 800 MPa.
Q: Can these be used with aluminum parts?
A: Yes, but we suggest using a washer to prevent galvanic corrosion between steel and aluminum.
Q: Do you stock M22 sizes?
A: No, this listing covers sizes from M3 up to M20 only.
Q: What size Allen key is needed for M10 bolts?
A: For M10 hex socket screws, you will typically need an 8mm Allen key.
Q: Are these suitable for outdoor exposure?
A: Zinc plating provides basic corrosion resistance, but for harsh outdoor environments, stainless steel is recommended.
