Bulk packing, mixed-size cartons, palletized shipment, and bolt-nut-washer sets are available upon request.
Quick Specs
What Buyers Should Know Before Sourcing JIS B1256 Flat Washers
JIS B1256 flat washers are used to distribute load under bolt heads or nuts, reduce surface damage, and support more consistent fastening in metric assemblies. When reviewing fastener products, buyers should confirm washer inner diameter, outer diameter, thickness, material, finish, hardness condition, and whether the washer will be used with a specific bolt or nut standard.
For factory supply, washer tolerances and surface finish should be checked against the mating part and application environment. If the project requires modified thickness, enlarged outside diameter, special coating, or drawing-based geometry, XZ Fastener can review related custom fasteners together with the standard washer request.
Procurement Checklist
- Confirm nominal size, inner diameter, outer diameter, and thickness.
- Specify carbon steel, stainless steel, or hardened washer requirement.
- Match finish to the bolt, nut, and installation environment.
- Check if washers must be packed with bolts and nuts as sets.
- Provide carton label, bag quantity, and pallet requirements for bulk orders.

Material and Grade Explanation
Carbon steel JIS B1256 flat washers are often used in general machinery, brackets, frames, and industrial hardware. Hardened washers may be selected for higher clamp load or assemblies using higher strength bolts. Stainless steel washers are suitable for applications where corrosion resistance, appearance, or clean assembly conditions are important.
When washers are ordered together with bolts and nuts, the material and finish should be matched across the assembly. Buyers handling multiple standards can use the DIN and ISO fastener standards guide as a reference for related metric terminology, while final JIS B1256 dimensions should still be checked against the project drawing.
Material Selection Notes
- Carbon steel is practical for general indoor and protected assemblies.
- Hardened washers help resist deformation under higher clamp loads.
- Stainless steel options can be reviewed for moisture or clean equipment use.
- Material grade and finish should be specified clearly for repeat orders.
Surface Finish Selection Guide
General Industrial Finishes
Zinc plated JIS B1256 flat washers are commonly used for machinery, equipment cabinets, brackets, and general hardware. Plain or oiled washers may be selected for controlled indoor environments or further processing. Black oxide washers can be supplied for a dark appearance with light oil protection.
Outdoor and Coated Assemblies
Hot dip galvanized washers are often used with galvanized bolts and nuts in outdoor steelwork and construction hardware. Coating thickness can affect washer stacking and assembly appearance, so buyers should review the complete fastener set. Related coated fasteners can be quoted together for consistent finish planning.
Manufacturing and Quality Control
JIS B1256 flat washers are produced through material preparation, blanking, punching, deburring, heat treatment when required, surface finishing, inspection, and packing. For factory orders, XZ Fastener can sort washers by size, material, finish, carton label, batch, and pallet plan according to order requirement.
Quality checks usually focus on inner diameter, outer diameter, thickness, burr condition, flatness, surface condition, hardness where required, and packing accuracy. Washers can also be supplied with industrial bolts and nuts when the buyer needs complete assembly hardware from one purchasing list.
Typical Inspection Points
- Inner diameter, outer diameter, and thickness measurement.
- Burr, edge condition, flatness, and surface appearance check.
- Hardness review for hardened washer requirements.
- Coating appearance and coating thickness review when specified.
- Quantity, carton label, and pallet layout verification before shipment.
Приложения
- Machinery frames, equipment bases, motor mounts, and guard panels.
- Automotive, motorcycle, agricultural, and transport hardware.
- Steel brackets, support plates, construction hardware, and maintenance assemblies.
- Distributor inventory, MRO kits, and bolt-nut-washer packing sets.
JIS B1256 flat washers are frequently used with JIS B1180 bolts, JIS B1181 nuts, threaded rods, and screw assemblies. When the same project includes foundation or concrete fixing work, related industrial anchors can also be reviewed with the washer and bolt order.
