A spring plunger is a small, threaded body component containing a spring-loaded ball or nose that projects from one end. When the ball or nose is pushed against a mating surface or detent, the internal spring lets it retract and then return, providing a controlled, repeatable holding, locating, or indexing force. Compact yet versatile, spring plungers are widely used wherever parts need to be positioned, held, or released quickly without complex mechanisms.
View DetailsSend InquiryA Cotter Pin (also called a Split Pin or Tongue Pin in some regional terminologies) is a metal fastener with a looped head and two tines (legs) that are bent to secure it in place. It is inserted through a pre-drilled hole—typically in a clevis pin, castle nut, or shaft—and the tines are bent outward to prevent loosening or withdrawal.
View DetailsSend InquiryA Clevis Pin is a cylindrical, unthreaded fastener with a formed head at one end and a transverse hole (or holes) at the opposite end. It is designed to be inserted through the mating lugs or fork of a clevis and secured with a cotter pin or lynch pin through the cross-hole to prevent axial withdrawal.
View DetailsSend InquiryA cylindrical pin (commonly known as a dowel pin or parallel pin in international trade) is a solid, precision-machined fastener with a uniform diameter along its entire length. It is primarily used for alignment, positioning, and load transfer between two or more components, rather than for clamping or fastening like a screw or bolt.
View DetailsSend InquiryA wood screw is a threaded fastener specifically engineered for joining wood to wood, or for attaching hardware, hinges, and fixtures to timber and wood-composite substrates. Unlike self-tapping screws designed for metal or plastic, the wood screw features a coarse thread pitch, a partially threaded shank, and a sharp, tapered point that cuts or displaces wood fibers to form a secure, friction-based mechanical lock within the material itself.
View DetailsSend InquiryA self-drilling screw is a hardened fastener featuring an integral drill point at its tip, designed to drill, tap, and fasten in a single operation—eliminating the need for a pre-drilled pilot hole. This "three-in-one" capability makes it the most efficient solution for joining metal-to-metal, metal-to-wood, and metal-to-composite applications in high-volume construction and industrial fabrication.
