A2-70 Stainless Steel Hex Socket Screw – Cylinder Head with Straight Knurling for Precision Machinery

A2-70 Stainless Steel Hex Socket Screw – Cylinder Head with Straight Knurling for Precision Machinery

Product Overview

Our A2-70 Stainless Steel Hex Socket Screw is engineered for high-torque, corrosion-resistant fastening in precision machinery and critical assemblies. Featuring a cylindrical head with straight knurling for enhanced grip and a hex socket drive for precise torque control, this screw is ideal for applications requiring durability, repeatability, and tool-free adjustability. Crafted from A2-70 (304) stainless steel, it excels in medical, aerospace, optical, and industrial machinery exposed to harsh environments or frequent adjustments.

Key Features

✅ A2-70 Stainless Steel (304 Grade)

  • Corrosion Resistance: Resists rust, humidity, and chemicals, ensuring longevity in labs, cleanrooms, or coastal settings.
  • High Tensile Strength: 700 MPa tensile strength for structural integrity under dynamic loads.

✅ Cylinder Head with Straight Knurling

  • Tool-Free Adjustments: Knurled grip allows manual tightening/loosening in tight spaces without tools.
  • Secure Handling: Textured surface prevents slippage during assembly or maintenance.

✅ Hex Socket Drive (Allen Key)

  • Precision Torque Control: Compatible with standard hex keys for high-torque applications without stripping.
  • Flush Mounting: Low-profile cylindrical head sits seamlessly with surfaces.

✅ Precision Machining

  • CNC-Turned Threads: ±0.02mm tolerances for perfect alignment in high-precision assemblies.
  • Smooth Finish: Passivated or electropolished surface reduces friction and bacterial adhesion.
