Good to know
- Coarse (UNC) thread — faster to install and more tolerant of nicks and corrosion.
- Accepts a cotter pin through a cross-drilled bolt for a positive, vibration-proof lock.
- Plain finish has no corrosion coating — oil, wax, or paint for outdoor or wet service, or ask us about a plated option.
