Radium Electrical Bulkhead Stud Kit — 8-Pack This kit includes 8 complete electrical bulkhead stud assemblies, each CNC-machined from 304 stainless steel for electrical conductivity and long-term corrosion resistance. Designed for clean, reliable bulkhead wiring pass-throughs in fuel cells, firewalls, and chassis panels, these studs are compatible with all fuel types including gasoline, diesel, E85, ethanol, and methanol. Each stud includes a special insulating sleeve to prevent panel conduction and galvanic corrosion, a ring terminal accepting 10-12 AWG wire, two top locking nuts for a secure connection, a nylon acorn nut, and heat shrink to insulate exposed areas from accidental shorts. Important — Dimensional Requirements: The following panel specifications must be met for correct installation: Drilled hole diameter: 0.220"-0.234" (15/64" drill bit) Material thickness: 0.262"-0.322" Suits: Universal — fuel cells, firewalls, and chassis panel bulkhead wiring applications Kit Includes (per stud — x8 sets): CNC-machined 304 stainless steel bulkhead stud Insulating sleeve (prevents panel conduction and galvanic corrosion) Ring terminal (10-12 AWG) 2x top locking nuts Nylon acorn nut Washers Heat shrink Available Part Numbers: 17-0048 — Electrical Bulkhead Stud Kit, 8-Pack Why Radium Engineering? ✅ Manufactured in the USA to motorsport-grade tolerances ✅ CNC-machined 304 stainless steel for electrical conductivity and corrosion resistance ✅ Trusted by tuners and race teams running high-power builds worldwide ✅ Insulating sleeve prevents galvanic corrosion and panel shorts — safe for all panel materials ✅ Compatible with all fuel types including E85, ethanol, methanol, diesel, and pump petrol
