Clinch Fastener Selection Guide Based On Sheet Thickness & Hole Dimension Standard

Clinch Fastener Selection Guide Based On Sheet Thickness & Hole Dimension Standard

Improper selection and wrong pilot hole size are top causes of clinch failure; this guide classifies fastener options by sheet thickness.

1. Ultra-thin sheet 0.5~1.0mm

Low-profile mini clinch nuts and screws are recommended with strict pilot hole tolerance to avoid sheet crack during pressing.

2. 1.2~2.0mm sheet for standard SO through-hole studs

SO open clinch studs with standard pilot hole for indoor dry cabinet with cost advantage.

3. 2.0~3.0mm sheet for BSO sealed waterproof studs

Closed-bottom BSO studs prevent water and dust penetration, ideal for outdoor energy storage equipment.

4. Troubleshooting common clinching defects

Cracked sheet comes from oversized hole; loose fastener results from mismatched part thickness, replace correct specification accordingly.
