Wenzhou Yuanzhi Auto Parts Co. Ltd manufactures hex socket oil pipe plugs in carbon steel, alloy steel, stainless steel, brass, and other materials as specified. The plugs feature a hex socket (Allen) drive and are designed for sealing threaded oil passages in automotive and industrial hydraulic systems. The product line includes sizes from 1/16 inch to 1 inch, with multiple finish options including zinc plating, black oxide, and hot-dip galvanizing. Each plug is precision-machined to meet DIN and ISO dimensional standards.
The material selection varies by application: carbon steel (C70, 65Mn) is used for general-purpose plugs, while stainless steel and brass are specified for corrosion resistance. Heat treatments such as tempering and carburizing are applied to improve hardness and wear resistance. Surface finishes include plain, passivated, chrome-plated, and nickel-plated options. Tolerances follow standard machining practices for threaded fasteners, with thread pitch and diameter conforming to GB, ANSI, and JIS standards.
These plugs are purchased by automotive OEMs, aftermarket parts distributors, and industrial equipment manufacturers. Buyers require consistent thread engagement, leak-free sealing under pressure, and dimensional accuracy. Orders are accepted in small quantities, with packaging options from 100 to 1,000 pieces per bag, packed in export cartons. Samples are available for quality validation before bulk orders, and OEM/ODM customization is supported for non-standard sizes or finishes.
