Ellie ★★★★★

Bought these to replace worn-out screws on a CNC fixture and the 10.9 alloy steel is noticeably tougher than standard hardware—no stripping even under repeated torque. The hex drive seated cleanly without slipping.

Eli ★★★★★

Bought these for a batch of jigs after my last lot stripped mid-job, and the Class 10.9 alloy steel feels noticeably sturdier when I’m torquing them down.

The hex socket drive on these M4 screws gave me a solid bite without any cam-out while assembling a precision fixture. Zinc coating looks clean and uniform across all 600 pieces, which is exactly what I needed for a consistent build.
