Left Hexagon Socket Shoulder Screw is a specially designed fastener with left-handed thread and stepped shoulder, mainly used in mechanical structures that require high-precision positioning and reliable fixing.
Features
Left-handed thread: Unlike traditional right-handed screws, it is suitable for special mechanical designs to prevent loosening.
Stepped shoulder: Provides precise axial positioning, suitable for fixing rotating or sliding parts.
High-precision manufacturing: Strict control of dimensional tolerances to improve assembly accuracy.
Surface treatment: Blue zinc plating (BLUE ZINC PLATING) is used, which has good corrosion resistance.
Excellent corrosion resistance: Salt spray test time exceeds 72 hours, suitable for high salt environment.
Advantages
Anti-loosening design: Left-handed thread can prevent loosening caused by vibration and improve fastening stability.
High-strength material: Made of low-carbon steel, it has good toughness and mechanical properties.
Adapt to a variety of industry standards: Meets JIS/ANSI/DIN/BSI standards and is suitable for the global market.
Precise size control: M3 diameter, pitch 0.5mm, shoulder length 8mm, strict tolerance control to ensure installation matching.
Excellent surface protection: blue zinc plating provides good oxidation resistance and prolongs service life.
Scope of use
Precision mechanical equipment: such as bearing seats, sliding guides, positioning components, etc.
Automobile manufacturing: used for key fastening parts to prevent loosening due to vibration.
Electronic equipment: used to fix precision parts to prevent loosening from affecting performance.
Aerospace: suitable for high-demand fastening applications to improve structural stability.
Industrial automation: used for connecting parts of robots and automation equipment to provide high-precision positioning.
Support customization
Size customization: different lengths, diameters and pitch specifications can be provided according to customer needs.
Surface treatment customization: different surface treatments such as galvanizing, blackening, and nickel plating can be provided to meet different environmental requirements.
Material selection: materials such as stainless steel and high-strength alloy steel can be selected to improve corrosion resistance or strength.
Thread type: support customization of different left-hand thread specifications to meet special assembly needs.
FAQ
Q1: Why does the Left Hexagon Socket Shoulder Screw use left-handed threads?
A1: Left-handed threads are suitable for scenarios where screws need to be prevented from loosening, especially in equipment with large vibrations, to ensure the stability of fasteners.
Q2: How is the corrosion resistance of this screw?
A2: It adopts blue zinc electroplating surface treatment and salt spray test for more than 72 hours. It has strong anti-oxidation ability and is suitable for humid or high-salt environments.
Q3: How to choose the right size?
A3: When choosing the right size, you need to consider the screw diameter (M3), pitch (0.5mm), shoulder length (L8mm) and thread length (L6mm) to ensure that it matches the equipment.
Q4: Does it support customized specifications?
A4: Yes. Different diameters, lengths, thread specifications and surface treatment processes can be customized according to customer needs to adapt to different application scenarios.
Q5: How to ensure product quality?
A5: The products comply with international standards such as JIS, ANSI, DIN, BSI, etc., and adopt strict quality inspection to ensure that the dimensional accuracy, material strength and surface protection performance meet the requirements.
Q6: What are the common maintenance problems?
A6:
Loose screws: Check the tightness of the screws regularly to ensure that they will not loosen due to vibration.
Corrosion problem: Although it has an anti-rust coating, it is still necessary to check the surface regularly for rust in extreme environments.
Installation problem: Use a matching hexagonal tool during installation to avoid using excessive torque to damage the screws.
