When possible it is always best to select a standard catalog item due to availability and cost. However, if your design requires a modification of the material, dimensions, performance properties, corrosion resistance requirements, or any other reason, a special self clinching fastener can be developed. Our engineering staff will work closely with you and will offer suggestions based on the criteria you provide. We will offer a print for your review and approval before any production is started. We look forward to working with your engineering department to provide a solution.
