PEEK Flat Washer
The PEEK Flat Washer (polyetheretherketone flat gasket) is an insulating and corrosion-resistant washer made by JINGHONG FASTENERS from high-performance PEEK engineering plastic. It covers specifications from M2 to M20 metric threads. This product has excellent high and low temperature resistance (long-term operating temperature approximately 260℃), high mechanical strength, and extremely low water absorption. It can maintain stable size and insulation performance even in high-temperature, humid or chemically corrosive environments. It is mainly used in electronic and electrical, semiconductor equipment, medical devices, and chemical pump valves and other scenarios, serving as an insulating isolation layer beneath bolts or nuts to prevent electrochemical corrosion and distribute the connec......

Flat Head Solid Copper Nails
Our factory specializes in producing copper flat head solid rivets, which are formed by cold heading using H62 brass, H65 brass or purple copper rods. The head is a flat head cylindrical shape, which is flat and stable after riveting, suitable for connection parts that need to withstand certain tensile and shear forces. The surface of the product can be treated with nickel plating, green antique copper, red antique copper, etc. The specifications range from 2mm to 10mm, and the length can be customized according to the thickness of the workpiece. There is ample stock of regular sizes, and non head diameter and rod diameter customization are supported.

GB1099 Woodruff Key
GB/T 1099 Woodruff Key (commonly known as "moon key") is a standard mechanical transmission component in the shape of a half-moon, used to achieve circumferential fixation and torque transmission between the shaft and the hub (such as gears, pulleys). Its working surface is two parallel planes on both sides, and the bottom is an arc structure. It has the ability to automatically compensate for misalignment, can adapt to small assembly deviations, and is particularly suitable for cone shaft end connections with high alignment requirements. This key significantly weakens the shaft's strength and is mostly used to transmit medium to small torques or as auxiliary transmission components. It is widely used in the light-load transmission parts of motors, reducers, automotive components, and vari......

Square Taper Washers for U-sections
DIN 434 galvanized Square Taper Washers for U-sections are standard components specifically designed for bolt connections of channel steel (U-shaped steel). They are made of galvanized carbon steel and automatically compensate for the angle deviation of the channel steel flange through 10°/12° inclined surfaces, converting the axial force of the bolt into radial supporting force, effectively dispersing stress, preventing the channel steel from collapsing, and enhancing the shear resistance of the connection. They are widely used in steel structure projects such as construction, machinery, power, and rail transportation.

Hexagon Socket Set Screws with Cone Point
The stainless steel Hexagon Socket Set Screws with Cone Point are made of 304/316 stainless steel and are installed with high torque through the internal hexagon drive. Their sharp conical ends can actively penetrate the surface of the mating part, forming a strong mechanical lock, providing excellent vibration resistance, anti-loosening and precise positioning capabilities. After installation, the head can fully sink into the workpiece, meeting the requirements of compact space, and are widely used for positioning of transmission shafts, fine adjustment of precision instruments and axial locking of automation equipment.

Stainless Steel/Copper Weld Studs
Stainless Steel/Copper Weld Studs (convex welding screws/welding screws), with circular convex points or V-shaped sharp corners at the bottom, can be directly welded to the surface of metal plates with resistance welding equipment. After welding, a permanent threaded connection point is formed without the need for tapping, riveting, or backside operation. 304 stainless steel is rust resistant and corrosion-resistant, and copper material has excellent conductivity.
