Buying & RFQ guide
Control the washer and mating-joint requirement
Select by controlled dimensions and assembly requirements—not by appearance or a commercial name alone.
Standard washer enquiry
Identify the quotation basis and mating assembly.
- Standard number, edition and washer form or series—or drawing revision
- Nominal size and critical dimensions or tolerances
- Material, hardness, heat-treatment condition and finish
- Mating-fastener requirement, quantity, packing and documents
Custom & drawing-based washers
XHT reviews washer projects against buyer-controlled input.
- Approved drawing or sample with ID, OD, thickness and tolerances
- Required flat, chamfered or split form, section and end geometry
- Material, hardness or heat treatment, and finish or coating
- Quantity, packing, destination, inspection and document requirements
Specification control: Washer standards, forms and commercial names are not automatically interchangeable. Functional suitability and any locking or sealing performance must be confirmed for the actual joint and buyer-approved requirement.
