Prime-Line 9073318 Hex Nut 1/4"-20

These hot-dipped galvanised Grade A steel hex nuts come in a 100-count pack. The UNC-2B coarse threads fit standard 1/4"-20 bolts, cap screws or threaded rod. They meet ASME B18.2.2 and ASTM A563 Gr A specifications for general-purpose fastening. The protective coating resists corrosion in outdoor or damp environments.

Suits general repairs, not heavy structural loads

Ideal for maintenance, assembly and light construction where a standard finished nut is specified. Builders needing heavy-duty hex nuts or fine-thread variants should look elsewhere. The Grade A rating covers routine clamping force, not high-strength structural joints. Pack quantity is fixed at 100 pieces.

Key spec: 1/4"-20 UNC-2B thread size

This single dimension decides fit — match it exactly to the male threads on your hardware. The hot-dipped galvanised finish adds corrosion protection for exterior use. Grade A steel provides standard holding power per ASTM A563. Verify thread pitch and diameter before ordering.

Questions about this item

What size bolt, cap screw, or threaded rod do these 1/4"-20 nuts screw onto?

They screw onto any bolt, cap screw, or threaded rod with a matching 1/4"-20 coarse thread.

Can I use these Grade A galvanized nuts with older Grade 5 or Grade 8 bolts I already have?

Grade A nuts are lower strength than Grade 5 or Grade 8 bolts, so the nut will likely yield before the bolt reaches full capacity.

How do I verify the nuts meet the ASME B18.2.2 and ASTM A563 Gr A standards after I receive them?

Check the packaging for the ASME B18.2.2 and ASTM A563 Grade A markings that confirm the specification compliance.
