How to choose
- Thread: match diameter and pitch to the bolt — USS (coarse) and SAE (fine) inch threads do not mix, and metric nuts are sized like M8-1.25 (diameter in mm, pitch in mm).
- Finish: zinc-plated for dry indoor use, hot-dipped galvanized for outdoor and galvanized bolts (HDG nuts are tapped oversize to fit), stainless for wet or washdown areas.
- Lock nuts: use nylon insert lock nuts on machinery, carts and anything that vibrates; they are generally meant for one-time use.
- Wing nuts: pick wing nuts where a fastener is loosened and tightened by hand, such as guards and jigs.
- Grade: match the nut grade to the bolt grade on structural or high-load joints.
