Description
The Vcoil G (BSP) STI-Taps Thread Repair Kit is a purpose-built solution for restoring damaged or worn threads in metal parts. It uses stainless steel wire thread inserts (DIN 8140) to create new, stable internal threads that withstand regular service in maintenance, installation, and small‑batch production. Thread Armour Plating is specifically crafted for materials with low shear strength, helping protect the repaired threads and extend component life.
The kit includes a set of two stainless steel wire thread inserts (1.5D) sized for G1/4x19 BSP threads. These inserts follow ISO 2 (6H) tolerance and Type S specification, and they accommodate applications up to M12. Optimized for hand thread cutting, the kit is offered with high stock availability for standard and special dimensions, all neatly organized in a presentation case for quick access and field or workshop use.
- DIN 8140 stainless wire thread inserts: Restore damaged threads with new, stable internal threads and improved load capacity using precision-fit inserts (ISO 2 – 6H, Type S).
- Thread Armour Plating for low-shear materials: Special plating protects threads in soft or weak materials, reducing the risk of further damage and enabling reliable repairs.
- Versatile, up-to-M12 sizing in a portable case: Includes two 1.5D inserts for G1/4x19 BSP, supports dimensions up to M12, and comes in a sturdy presentation case with high stock availability for standard and special sizes for easy hand threading.
Using this repair kit, damaged holes can be quickly restored with robust stainless steel inserts, enabling secure fastener seating and lasting performance. The inserts offer corrosion and temperature resistance, helping maintain reliability in demanding environments. The organized presentation case reduces downtime by keeping all components readily accessible, making maintenance, installations, and small production runs faster and more predictable.
