BEM Auto's Loc-Sure body is fully machined from aluminum bars at the BEM Auto factory and is finished in a generic green anodized surface, etched to identify the assembled unit as a diesel only cap.  The Spin-Loc is fully machined from robust black acetal and etched for easy identification (all internal components between the acetal are stainless steel). The Secure Screw is manufactured from 18-8 stainless steel to provide good corrosion resistance.
