Knurled Cup Point Grub Screw, also known as hexagonal knurled cup head set screw, is a headless, threaded fastener. One end of the screw is cup-shaped (cup point) with a knurled design to enhance its anti-slip and anti-loosening performance during assembly. Its main function is to fix parts on shafts or other components to prevent sliding or rotation.
Function
Fixed positioning: widely used to locate components or prevent mechanical parts from shifting during operation.
Anti-loosening and anti-slip
Knurled Cup Point Grub Screw increases friction through the knurled structure, effectively preventing the screw from loosening due to vibration or load; the cup-shaped end is embedded in the surface of the fixed object to improve contact stability and prevent slipping and displacement. Its headless design fits compactly and is suitable for high-vibration and high-precision positioning occasions.
Not easy to damage the workpiece
Knurled Cup Point Grub Screw adopts a cup-shaped end design with a smooth contact surface. It can provide sufficient locking force while reducing indentations or scratches on the workpiece surface. It is gentler than pointed or conical screws and is suitable for precision equipment or soft materials that require surface protection.
Strong concealment: headless structure, almost flush with the surface after screwing in, suitable for occasions with high appearance requirements.
Material
Low carbon steel SWCH18A-22A
Features: good toughness, easy processing, suitable for most medium and low strength applications, high cost performance.
Surface Treatment
BLACK ZINC PLATING
Beautiful appearance and excellent anti-rust performance.
Salt spray test: more than 256 hours, suitable for high corrosion protection environment.
Head shape and type
Hex socket
Tighten with a hex wrench or hex tool, easy to install, suitable for small space areas.
Headless design, no protrusion on the surface after installation.
Thread Type
Metric Thread
Metric threads such as M2 and M3 are common in Asian and European standards.
Pitch example: 0.5mm.
Reference Standard
JIS B1111 / ANSI 18.6 / DIN7981 / DIN912
Covering Japanese, American, German and other national standards to meet the needs of different customers.
Advantages
The knurled structure enhances friction and prevents loosening;
The cup-shaped end improves contact stability and protects the contacted surface;
A variety of specifications and materials are available to meet personalized needs;
The black zinc treatment on the surface improves corrosion resistance and extends service life;
After tightening, it is well concealed and suitable for products with high appearance requirements.
Application
Electronic products
In electronic products, Knurled Cup Point Grub Screw is often used for positioning and fixing micro transmission shafts, knobs, connectors and other parts. Its compact headless design is easy to embed in a small space. The knurled and cup point structure ensures stable fastening, no loosening, no slipping, and avoids damage to precision parts. It is widely used in smart wearables, mobile phone components, electric motors and sensor structures.
Household appliances
In household appliances, Knurled Cup Point Grub Screw is mainly used to fix motor shafts, knobs, shafts and moving parts, such as fans, washing machines, power tools, etc. Its knurled cup point design can firmly lock parts, prevent loosening and slipping, and the cup-shaped end reduces the indentation on plastic or metal parts, prolongs product life, and improves operating stability. It is suitable for scenes with high vibration and frequent operation.
Mechanical equipment
In mechanical equipment, Knurled Cup Point Grub Screw is often used for precise positioning and fixing of moving or rotating parts such as sleeves, couplings, gears, and slide rails. Its knurled cup point structure can enhance friction and prevent loosening and sliding caused by vibration or load; the cup-shaped end can also reduce damage to the shaft surface, which is suitable for industrial equipment with high-frequency operation and high-precision requirements, and is widely used in automation equipment, CNC machine tools, transmission systems and other fields.
Automobiles and electric vehicles
In automobiles and electric vehicles, Knurled Cup Point Grub Screw is widely used to fix motor shafts, steering systems, brake components, sensor installation and interior parts. Its knurled structure provides strong anti-loosening force to adapt to the vibration environment when the vehicle is running at high speed; the cup-shaped end is close to the workpiece, fixed firmly and not easy to damage the surface of the part, suitable for precision parts positioning and systems with high requirements for structural stability, improving the safety and durability of the whole vehicle.
Hardware connectors
In hardware connectors, Knurled Cup Point Grub Screw is mainly used for the stable connection and positioning of small bearings, handles, door locks, hinges, adjusters and other parts. Its knurled surface enhances the locking friction to prevent loosening, and the cup-shaped end is firmly fixed without damaging the connection surface. Applicable to hardware structures that need to be frequently disassembled or adjusted, ensuring tight, stable and durable connections, and improving the overall assembly quality and service life.
Medical devices
In medical devices, Knurled Cup Point Grub Screw is often used to fix and position precision parts, micro transmission devices, brackets, adjustment mechanisms and other structures. Its compact headless design is suitable for installation in compact spaces, the knurled structure enhances the anti-loosening performance, and the cup-shaped end effectively fixes while reducing the indentation on the surface of the instrument, protecting the precision components from damage. It is widely used in surgical instruments, dental equipment, rehabilitation aids and laboratory instruments to ensure stable structure, precise operation, safety and reliability.
