  • It is processed by STAR dual-spindle CNC centering machine, the cylindrical cutter with 55°R0.2 corner is used for finishing the end face, processing the outer diameter, the 90°tungsten steel center drill is used for centering, the tungsten steel bit is used for drilling, then use the rotary punch to process the inner hexagon,then remove the burr in the hole with a tungsten-carbide bit, and then use the R0.4 corner turning tool to rough the outer diameter of the thread, for the secondary shaft, use a cylindrical cutter with 55°R0.2 corner to process the outer diameter of the thread, finish the end face, and then use a thread cutter to process the thread, and then use a cylindrical cutter with 55°R0.2 corner to remove the thread burr, and then use a thread cutter to remove the thread burr.
    Specializing In The Production Of Stainless Steel Contour Screws, End Cross, Plum And Hex Can Be Produced. Hexagon Socket Screws Are Often Used In Machinery, And Have The Advantages Of Easy Fastening, Disassembly, And Not Easy To Slip Corners. The Allen Key Is Generally A 90 ° Turn. One End Of The Bend Is Long And The Other End Is Short. When Screwing With The Short Side, Holding The Long Side Can Save A Lot Of Force And Tighten The Screw Better. The Long End Has A Round Head (hexagon Cylinder Is Similar To A Ball) And A Flat Head. The Round Head Can Be Easily Inserted Into The Screw Hole For Easy Removal. The Manufacturing Cost Of The Outer Hexagon Is Much Lower Than That Of The Inner Hexagon. Its Advantage Is That The Screw Head (the Stress Position Of The Wrench) Is Thinner Than The Inner Hexagon, And Some Places Can Not Be Replaced By The Inner Hexagon. In Addition, The Inner Hexagon Screws Used By Machines With Low Cost, Low Power Strength And Low Accuracy Requirements Are Much Less Than The Outer Hexagon.
    Material:  SUS304(1.4301)/SUS316(1.4404) Specification:  OD 10*M6 (customized according to customer size)

What is cold heading fasteners

Cold heading fasteners, also known as cold-formed fasteners, are specialized types of fasteners that are manufactured using a cold-heading process. Cold heading is a method of forming metal parts at room temperature without the need for heating or excessive force. It involves shaping metal wire or rod material into the desired fastener shape by utilizing a series of dies and punches.
Cold heading fasteners are commonly used in various industries and applications, including automotive, construction, electronics, and appliances. They are available in a wide range of types, such as screws, bolts, nuts, rivets, and pins.
The cold heading process offers several advantages for fastener production. It allows for high-speed and cost-effective manufacturing, as large quantities of fasteners can be produced in a short period. Cold heading also provides improved material strength and hardness, as the metal is work-hardened during the forming process. Additionally, the absence of heat during production prevents material degradation and maintains the integrity of the fastener.
Cold heading fasteners are known for their reliability, strength, and dimensional accuracy. They are typically made from steel, stainless steel, aluminum, or brass, depending on the specific application requirements. These fasteners can be found in numerous everyday products, from automobiles and machinery to consumer electronics and household appliances.

What is cold heading parts

Cold heading parts, also referred to as cold-formed parts or cold-extruded parts, are components that are manufactured using the cold heading process. Cold heading is a metal forming process where metal wire or rod material is shaped into a specific part without the need for heating.
The cold heading process involves feeding a length of metal wire or rod into a machine called a cold heading machine. The machine then uses a series of dies and punches to shape the material into the desired part. The dies and punches exert force on the metal, causing it to flow into the desired shape while it remains at room temperature.
Cold heading parts can take various forms, depending on the specific application and design requirements. They can be simple or complex shapes, such as pins, bolts, screws, rivets, studs, or intricate components used in various industries.
The cold heading process offers several advantages for producing parts. It allows for high-speed and cost-effective manufacturing, as large quantities of parts can be produced quickly. Cold heading also results in improved material strength and hardness, as the metal is work-hardened during the forming process. Additionally, the absence of heat during production helps maintain the material's properties and integrity.
Cold heading parts are widely used in industries such as automotive, aerospace, electronics, construction, and appliances. They are known for their reliability, precision, and dimensional accuracy. These parts can be found in a wide range of products, from vehicles and machinery to electrical devices and consumer goods.

What is Stainless steel cold heading bolts

Stainless steel cold heading bolts are a type of fastener made from stainless steel and manufactured using the cold heading process. Cold heading is a metalworking process used to form metal parts, such as bolts, by shaping a piece of wire or rod material in a cold state.
Stainless steel is a popular material choice for cold heading bolts due to its corrosion resistance, durability, and aesthetic appeal. It contains a significant amount of chromium, which forms a passive oxide layer on the surface, providing excellent protection against rust and corrosion.
The cold heading process involves several steps. First, a length of stainless steel wire or rod is cut to the desired length. Then, the end of the material is shaped into a specific form, such as a bolt head or a threaded portion, using a cold heading machine. The cold heading machine applies force to the material, deforming it into the desired shape without the need for heating.
Once the initial shaping is complete, secondary operations may be performed to add features like threads, grooves, or other specific designs. These secondary operations can be done through various methods such as threading, rolling, or cutting.
Stainless steel cold heading bolts are commonly used in various industries, including automotive, construction, aerospace, and marine applications. They are appreciated for their strength, corrosion resistance, and ability to withstand harsh environmental conditions. These bolts are available in a wide range of sizes, thread types, and configurations to suit different applications and requirements.
