Thin sheet threads are where most panel projects stall
The sheet is too thin to tap, welding distorts the panel, and every rework costs days. Typical failure points we engineer around:
- Tapped threads in 1–2 mm sheet strip out under repeated assembly
- Weld nuts and arc welding pull, mark or burn thin and coated panels
- Blind locations cannot be reached from the reverse side at all
- Off-the-shelf specials arrive late, or arrive wrong and wait weeks for correction
Cold-formed fastening – three process lines, one factory
Helefastener builds the thread into the panel instead of fighting the sheet:
- Self-clinching – nuts, studs and standoffs pressed into round holes; flush, permanent, load-bearing threads in sheet from about 0.5 mm
- Blind rivet nuts – single-side installation for tubes, extrusions and closed profiles, M3–M16
- CD weld studs – capacitor-discharge studs that weld in milliseconds with no reverse-side mark on coated and finished panels
Every part is manufactured against GB, ISO, ASTM, DIN and SAE equivalents, so drawings written around PEM, PSM and comparable catalogues can be sourced directly.

Common questions, answered up front
Will the parts interchange with branded catalogues? Our self-clinching series follows the same installation logic and dimensional logic, so existing hole charts and tooling carry over; we confirm interchangeability on your drawing before sampling.
How do I verify quality before an order? Request free samples, run your installation test, and ask for material certificates with the batch. ISO 9001 governs the process behind them.
What is the minimum order? Standard catalogue items ship from stock in small quantities; specials are quoted per drawing – ask us instead of assuming a large MOQ.
Start with a sample, not a promise
Send your drawing or thread/panel specification through the quote form or WhatsApp. You will get a confirmed part number, lead time and free samples to test – then decide.
