Metric Hexagon Rivet Bushes BZP (Packs of 10)

Unbeatable Anti-Spin Design Tapping a thread directly into thin sheet metal is weak, and standard round inserts can sometimes spin if a bolt seizes or is over-tightened. The hexagon-shaped body of these rivet bushes features specific undercut points that bite directly into the panel. This gives you the practical advantage of extreme turning resistance, ensuring the insert will not spin under heavy tightening loads and providing a completely secure anchor point. Permanent Peened Locking Thin materials simply do not have the depth to support a secure threaded bolt, severely limiting your construction options. These bushes solve this by utilizing a thin spigot. Once the bush is seated in a pre-punched hole, this spigot is peened over (flared outward). This action securely locks the bush flush into the parent material, effectively transforming flimsy sheet metal into a robust load-bearing platform. Flexible, Economical Installation You do not need a massive, expensive industrial setup to utilize these professional fixings in your workshop. They are incredibly versatile and can be installed using either a traditional hammer and punch or a dedicated mechanical press tool. This makes them a highly economical choice for both large-scale commercial fabricators and small-scale custom metalworkers. Bright Zinc Plated (BZP) Protection Metal enclosures and fabrications are often subjected to moisture in busy workshops, garages, or industrial environments. The BZP finish provides a reliable sacrificial layer of zinc, shielding the underlying steel from rust and oxidation. This ensures your internal threads remain clean, smooth, and functional, preventing cross-threading caused by corrosion. Key Features Hexagon-shaped body with undercut points gives additional turning resistance. A thin spigot is peened over to securely lock the bush into the parent material. A simple and economical way of adding a metric thread to sheet metal. Highly versatile: can be installed using either a hammer or a press tool. Manufactured from durable steel with a Bright Zinc Plated (BZP) finish. Supplied in a highly convenient, project-ready pack of 10 bushes.
