Precision Machining Parts

Industrial-Grade Precision Custom Fastener Series

Features: Machining Processes; Forming Technology: Cold Forging or Hot Forging is utilized to ensure continuous metal grain flow, significantly enhancing the tensile strength of the fasteners.; Thread Machining: We employ precision thread rolling instead of cutting. This process induces compressive residual stress on the thread surface, remarkably improving fatigue resistance.; Secondary Machining: Secondary CNC turning and milling operations are performed for specific head geometries or ultra-tight tolerance requirements.

Description

Product Diversity & Features We offer highly customizable capabilities (Custom Fasteners), including: High-Torque Drive Systems: Features various Torx and Hex socket head designs aimed at providing superior torque transmission and preventing tool cam-out during installation. Specialized Point Designs: Certain bolts feature tapered or dog point structures, facilitating rapid self-location and seamless integration into automated assembly lines. Diverse Surface Treatments: Options include plain stainless steel, gold-colored coatings (e.g., Titanium Nitride / TiN for increased hardness and wear resistance), Black Oxide, and Electroless Nickel Plating. Micro Fasteners: Miniature screws specifically designed for the assembly of precision instruments and electronic devices.

Technical Tolerances For these industrial-grade precision fasteners, our strict tolerance control is as follows:

Thread Precision: Conforms to international 6g / 4h tolerance classes.
Outer Diameter / Length Tolerance: ±0.01 mm.
Precision Feature Limits: For dowel pin sections or specialized flange faces, minimum tolerances can reach extremely tight limits of ±0.005 mm (5 μm).
Hardness Requirements: Available in high-tensile standards up to Property Class 10.9 or 12.9.

Product Technical Advantages

Ultimate Fatigue Resistance: An optimized thread root radius (R-angle) design minimizes stress concentration, extending component lifespan in high-vibration environments.
High Environmental Adaptability: Flexible material selection based on application requirements, including highly corrosion-resistant materials (e.g., A4-80 stainless steel) or high-temperature alloys.
Assembly Efficiency: Precise geometric dimensions guarantee exceptionally low jamming rates when fed into automated sorting and assembly lines.
