25Pcs Steel Multi Grip Rivet Nuts Pre Bulbed Shank Zinc-Plated Flat Head Threaded Insert Nut Construction Fasteners for Industrial (1/4-20)

In a recent test of the threaded inserts, the product received mixed reviews with users finding various applications for the item. One user was pleased with the inserts, using them to install tall seats in a John boat for added support and anchoring them to thin aluminum seat material. The design of the inserts with a larger top flange and even larger bottom flange provided a strong threaded support for the seat base. Another user found them useful for adding threads where they were needed, successfully mounting items like E brakes and fuel filters. The inserts were also commended for their quality and timely delivery. However, the product did face some criticism from users who experienced issues with durability. Some users reported crush nuts failing under pressure, resulting in bolt snapping. Others pointed out that the metal seemed cheap, requiring a specific tool for installation to prevent twisting and tearing. One user had multiple inserts fail, with one snapping and others experiencing thread damage. Despite the mixed reviews, the inserts were praised for being perfect for repairing broken or rusted out threads in various applications, such as a sewage basin. They were found to provide a secure grip, especially in plastic material, unlike other alternatives like rivnuts. However, some users did encounter challenges with using the inserts due to the length of the tool shank, requiring a custom solution for proper installation. Overall, while the threaded inserts showcased versatility and utility in various applications, there were concerns raised about their durability and installation requirements. **
