Quick Specs
What Buyers Should Know Before Sourcing JIS B1181 Hex Nuts
JIS B1181 hex nuts are metric nuts used when Japanese Industrial Standard dimensions or project-specific JIS references are required. Wholesale buyers should confirm nominal diameter, pitch, nut style, thickness, across-flat width, property class, finish, and mating bolt standard before production. XZ Fastener supplies related fastener products for bolt, nut, washer, screw, anchor, and threaded rod assemblies.
For coated assemblies, nut thread fit should be checked together with the mating bolt. Hot dip galvanized nuts may require special attention to tapping and assembly fit. If a project includes custom length bolts, special threads, or customer labels, XZ Fastener can review the full package through its custom fasteners service.

Material and Grade Explanation
JIS B1181 hex nuts can be supplied in carbon steel for general industrial fastening, alloy steel for higher-strength assemblies, and stainless steel for corrosion-resistant applications. Nut property class should be selected according to the mating bolt, required proof load, and service condition.
For common metric assemblies, buyers often pair JIS B1181 nuts with JIS B1180 hex bolts or other metric hex bolts according to drawing requirement. When buyers compare JIS, DIN, and ISO fastener requirements, XZ Fastener’s DIN and ISO fastener standards guide can help purchasing teams organize standard references before sending an inquiry.
Grade Matching Notes
- Use the drawing or project specification to confirm nut property class.
- Check bolt property class and washer requirement together with nut grade.
- Confirm thread pitch and fit before wholesale production.
- For galvanized assemblies, review nut tapping and bolt fit before packing.
Surface Finish Selection Guide
Surface finish affects appearance, corrosion resistance, storage performance, and thread fit. For nut and bolt assemblies, the coating should be confirmed across the full assembly. XZ Fastener can supply related coated fasteners when buyers need consistent surface treatment.
Plain or Oiled
Suitable for controlled storage, indoor assembly, and projects where the buyer applies separate protection after installation.
Zinc Plated
Common for clean appearance and basic corrosion protection in indoor or mild-service applications.
Black Oxide
Often requested for machinery, equipment frames, tools, and assemblies where a dark finish is preferred.
Hot Dip Galvanized
Used for outdoor and construction applications. Thread fit with mating bolts should be checked before wholesale shipment.
Phosphate
Can be reviewed for selected industrial assemblies where lubrication, paint adhesion, or dark appearance is required.
Special Coatings
Zinc-nickel, zinc-aluminum, Dacromet-type, or other coatings can be reviewed according to application requirement.
Manufacturing and Quality Control
JIS B1181 hex nut wholesale production requires control of raw material, forming, tapping, heat treatment where required, surface treatment, dimensional inspection, sorting, and packing. XZ Fastener checks size list, drawing notes, property class, thread pitch, finish, labels, and packing method before production confirmation.
Quality checks can include across-flat width, nut height, chamfer, thread pitch, thread gauge, visual appearance, coating appearance, and assembly fit with mating bolts. XZ Fastener can also supply related standard fasteners when buyers need bolts, nuts, washers, screws, anchors, and threaded rods in one shipment.
Common QC Items
