5 Pack M3 X 6mm X 1.2mm PEEK Socket Cap Hollow Screws High Temperature Corrosion Resistant Plastic Insulated Electrical Fasteners Badass Grade For Hot Rods And Cars

PEEK hollow socket caps for hot rod electrical systems
✔️ M3 x 6mm screw packs five units with 1.2mm inner bore size

These threaded insulators bring solid isolation to engine bay wiring and high heat environments. You will find them handy on custom hot rods, modified motorcycles, and race car builds where metal screws cause shorts or melt under exhaust temperatures.

✅ PEEK thermoplastic material handles intense engine heat without warping
✅ Socket cap head design accepts a hex key for secure tightening cycles
✅ Hollow core allows wire threading while keeping circuits electrically isolated
✅ Five piece inventory covers most aftermarket automotive repair jobs quickly

💡 What makes thermoplastic socket caps better than steel nuts for hot rod electrical setups?
Deploying advanced polymer fasteners keeps your underhood wiring clean and functional.
- High glass transition temperature prevents softening near turbochargers
- Electrically dielectric cores stop stray currents from frying modern ECUs
- Lubricant proof shells slide easily past fragile sensor lines during rebuild days
