Review on πŸ”© Irwin 1121ZR 6 48 Machine Screw: Unmatched Precision and Durability at Your Fingertips by Darrin Parasson

Revainrating 2 out of 5

Not good. good for fasteners

The tap was not very sharp. Even with a hole size for 50% thread, it sits quite accurately on the steel. I smudged the cut edges and crevice at the thread burr, which helped a little, but not much. Someone inexperienced in tapping would surely break this faucet.

Pros
  • Used where high precision and thread tolerance are not critical
Cons
  • Very expensive
