Carbon Steel Oil Drain Plug
-- Steady & Reliable Manufacturer --
Product Overview
This drain plug is machined from carbon steel and zinc or black oxide plated, giving a cost-effective option for OEM and high-volume aftermarket production where stainless steel's extra corrosion resistance is not required for the intended service life. It is produced across the common metric and unified thread sizes used on passenger car and light truck engines and transmissions.
We supply this plug to automotive aftermarket brands and OEM purchasing teams building cost-sensitive production runs, with private-label and custom packaging available for distributor resale.
