Mechanical Properties
Core Functions and Application
Heavy-Duty Fastening:
Works with Grade 8 bolts/studs to provide extremely high clamping force, withstanding strong tensile, compressive, and impact loads to ensure structural safety. Anti-Vibration and Anti-Loosening: High strength and stable thread engagement prevent loosening under continuous vibration and alternating loads, reduce the risk of failure.
Load Distribution:
Hexagonal structure and large support surface distribute preload, protecting the surfaces of connected parts. Standard Interchangeability: Complies with SAE J995 and ASME B18.2.2, featuring unified dimensions and performance for global compatibility and quick replacement.
Main Industry Application Scenarios
Automotive & Transportation:
Chassis, frames, engines, transmissions, suspensions, steering systems, withstand high-frequency vibrations and impacts.
01
Heavy Machinery:
Construction equipment, mining machinery, agricultural machinery, machine tools, lifting equipment, endure heavy loads and harsh working conditions.
02
Construction & Infrastructure:
Steel structures, bridges, factories, tower c, heavy-duty supports, provide long-term stable heavy-load connections.
03
Energy & Power:
Wind power, photovoltaic power generation, transmission towers, oil & gas pipelines, pressure vessels, chemical equipment suitable for high-stress and corrosive environments.
04
Rail Transit:
Locomotives, carriages, track fasteners, ensure connection reliability under high speed and vibration.
05
Core Features
- Material & Strength: Medium carbon alloy steel (e.g., SAE 4140), quenched high-temperature temped; Tensile ≥150 ksi (1034 MPa), Yield ≥130 ksi (896 MPa), Hardness HRC 29– approaching National Standard Grade 10.9.
- Marking: Two circumferential lines at 60° angle on the hexagonal face manufacturer's mark, facilitate on-site identification.
- Thread Precision: UNC/UNF Class 2B, ensuring smooth engagement, anti-galling, and repeated disassembly.
- Surface Treatment: Commonly galvanized / blackened / phosphated to enhance rust resistance; also available in hot-dip galvanizing or Dacromet for outdoor/corrosive environments.
- Specifications: 1/4"–1-1/2", covering mainstream heavy-duty connection requirements.
