Screw Thread

A) “ GRIPP^{® ”} Screw Thread Insert : Most light alloys and plastic materials are very low in shear strength. Consequently tapped threads in the material have poor pull strength and low resistance to wear.
“ GRIPP^®” wire inserts have been the preferred solution for strengthening threads in low-strength metal materials for over thirty years due to high-wearing tensile strength, low thread friction, tight tolerances and a high surface quality as well as corrosion and heat resistance. 
These inserts are formed by coiling a rhomboidically profiled wire into a resilient spiral coil resulting in an optimal fitting structural shape, hence the name coiled screw thread wire insert.
These coiled wire inserts provide a hard accurate lasting thread of high mechanical efficiency.
“ GRIPP ^{® ”} inserts are lighter, cheaper and occupy less space than a solid bushing, by locking itself permanently into position in a tapped hole, screw thread inserts do not require staking or locking pins which generally add to assembly weight and bulk.
“ GRIPP^{® ”} wire inserts are manufactured for every thread form including UNC, UNF, BSW, BSF, BSP, BA and ISO Metric threads.
wound screw thread inserts are manufactured from class 304 (18-8), 316 stainless steel as well as Inconel materials.
