Hex Nuts - Grade 8
Standard
Nylon
Lock
These Grade 8 steel hex nuts offer greater strength and durability than their Grade 5 counterparts. The zinc-yellow chromate coating offers a high level of corrosion resistance and rust protection.
The nylon lock insert in these hex nuts eliminates the worry of vibration loosening the nut. They're also reusable.
Split-Lock Washers
Split-lock washers decrease the likelihood that your fasteners will come unfastened by adding tension to the contact point. Made of high strength steel, with a zinc-yellow chromate finish.

Flat Washers
We offer two types of flat washers. Our premium washers are made of through-hardened high-strength steel and have a zinc-yellow chromate finish that provides superior corrosion and rust protection. Our more economical option is our steel washers with a zinc-clear coating that provides good corrosion resistance and rust protection.
SAE washers have a smaller ID and OD than their USS washer counterparts.
Large-diameter washers cover up oversized holes.
