Perfect Fit

Threads were clean and precise. The nickel plating gives a nice finish and some corrosion resistance.

Excellent Strength

Used these for a high-stress assembly on my CNC machine. The 12.9 grade held up perfectly under torque.

Good Value

Solid bolts but packaging was slightly damaged during shipping. The screws themselves were fine.

5 FAQ

Q: What is the thread pitch for the M10 size?

A: The M10 size features a standard metric coarse thread pitch of 1.5mm.

A: For M8 diameter socket head cap screws, a 6mm hex key is typically required.

Q: Are these screws made of stainless steel?

A: No, these are made of alloy steel with a nickel plating for strength and moderate corrosion resistance.

A: Yes, please contact our sales team directly for bulk pricing on large quantity orders.
