Fastener yamtunduwu, yomwe imadziwikanso kuti "zomangira zingwe zama waya zolumikizira chingwe". Zingwe zazingwe ndizida zapadera zomwe zimagwiritsidwa ntchito kulumikiza zingwe palimodzi. Kuphatikiza apo, mothandizidwa ndi cholumikizira ichi, malupu amapangidwa kumapeto kwa zingwe zomwe amagwiritsa ntchito.

Kapangidwe kamakhala ndi magawo atatu: mtedza, U-bulaketi ndi ulusi awiri ndi nsanja. Pulatifomu imayikidwapo koyambirira, kenako mtedzawo umakulungidwa. Zingwe ziwiri zazingwe zimayikidwa pakati papulatifomu ndi thupi la bulaketi. Kulimbitsa mtedza kumapangitsa nsanja kupondereza chingwe. Zotsatira zake, malonda amagwirizira chingwecho mosasunthika.
