Have plenty more for future use should I ever need it. Very sturdy build quality too. Review: Whoever invented this product needs to have a statue erected in their honor. - The kit contains a decent assortment of good quality coils. I used some to re-mount the starter to a riding mower. Loose bolts that wiggled each time the mower was started had stripped the threads from the holes in the engine block until the starter fell loose. These coils allowed me to repair the issue with a durable solution that could stand up to the vibrations and heat that made other options fail without having to re-tap the block to a larger bolt size, which would have not fit through the holes in the starter. Take time to do your homework and make sure you are using the right size. ## Features - High Quality: Thread repair inserts has deep thread, not loose, high-precision, strong anti-seismic, anti-impact and anti-abrasion functions, it can greatly improve the life of thread - Material: Wire thread inserts all made of 304 stainless steel, has good corrosion resistance, also has superior rust resistance and the excellent of oxidation resistance, avoid the damage of thread - Size: In thread repair kits, it include 7 size of M3 M4 M5 M6 M8 M10 M12 threaded inserts packed in a plastic box, each size sorted a grid separately. - Feature: Metric thread insert kit With certain elastic and even load, can make the load on the thread is more even, eliminate the screw and screw hole deviation between the pitch, thus increasing the screw thread connection strength - Application: Widely used in aviation, automobiles, steam turbines, electronic communications, computers, lamps, molds, mechanical equipment, radiators, and semiconductor equipment. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BPMKBV98 | | Best Sellers Rank | #45,587 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #3 in Thread Locking Inserts | | Brand | Zovfam | | Color | Silver | | Compatible Groove Diameter | 3/ 4/ 5/ 6/ 8/ 10/ 12 Millimeters | | Customer Reviews | 4.6 4.6 out of 5 stars (154) | | Fastener Type | Helical | | Finish Types | Nickel | | Grade Rating | industrial | | Item Diameter | 5 Millimeters | | Item Dimensions | 6.77 x 3.82 x 0.87 inches | | Item Shape | Round | | Manufacturer | Zovfam | | Material Type | Stainless Steel 304 | | Number of Pieces | 1 | | Screw Head Style | Round | | Size Name | M3 M4 M5 M6 M8 M10 M12 | | Thread Size | M3, M4, M5, M6, M8, M10, M12 | | UPC | 711691396982 | ## Product Details - **Brand:** Zovfam - **Color:** Silver - **Item dimensions L x W x H:** 6.77 x 3.82 x 0.87 inches - **Material:** Stainless Steel 304 - **Size:** M3 M4 M5 M6 M8 M10 M12 ## Images ![Wire Screw Sleeve Thread Repair Inserts Assortment Kit 304 Stainless Steel Metric M3 M4 M5 M6 M8 M10 M12 Wire Thread Inserts Helical Thread Repair Kit 210Pcs - Image 1](https://m.media-amazon.com/images/I/71W4D1RZTAL.jpg) ## Questions & Answers **Q: How durable are the inserts in this helicoil thread repair kit?** A: The inserts are made from 304 stainless steel, offering excellent corrosion resistance and long-lasting performance in high-stress environments **Q: Does this helicoil kit work for stripped threads in engine parts?** A: Yes, this helicoil thread repair kit is designed to fix stripped threads in engine blocks, spark plug holes, and other automotive components, restoring damaged threads without replacing expensive parts **Q: Is this thread repair kit suitable for aluminum materials?** A: This thread insert kit is ideal for aluminum thread repair, as the 304 stainless steel inserts provide strong, wear-resistant threads that improve durability and prevent future stripping **Q: What sizes are included in this metric thread repair kit?** A: This metric thread repair kit includes M3, M4, M5, M6, M8, M10, and M12 thread inserts, covering most common automotive, motorcycle, and machinery repair applications **Q: Can beginners use this stripped thread repair kit?** A: Yes, this stripped thread repair kit is beginner-friendly and includes the necessary tools like drill bits, taps, and installation tools for a complete repair process ## Customer Reviews ### ⭐⭐⭐⭐⭐ Saved my a$$ *by T***Y on March 2, 2025* Saved me when I stripped out a caliper bolt on my wife's jeep.
