Choose standard fasteners when an existing specification meets all functional, dimensional, and performance requirements. They are often the most economical solution for general-purpose applications and routine maintenance.
Consider custom fasteners when:
- Standard dimensions cannot fit the available installation space.
- The assembly requires special head shapes, shoulders, steps, grooves, or flanges.
- A component needs a unique combination of internal and external threads.
- Specific material, corrosion resistance, strength, or weight requirements must be met.
- Several functions need to be integrated into one fastening component.
- The application requires drawing-specific dimensions or tolerances.
Before ordering, provide the manufacturer with a technical drawing or sample, material and finish requirements, critical tolerances, estimated order quantity, and expected delivery schedule. These details help determine the most appropriate manufacturing process and cost structure.
