Component Specifications

Definition
A high-precision threaded fastener designed specifically for calibration mechanisms, enabling micrometer-level adjustments to align, position, or fine-tune machine components. It features precise thread geometry, minimal backlash, and consistent torque characteristics to maintain calibration accuracy under operational conditions.
Working Principle
Works through controlled rotational movement that translates into precise linear displacement via the screw thread. The fine pitch and tight tolerances allow for accurate incremental adjustments, while locking mechanisms prevent unintended movement after calibration.
Materials
Typically made from alloy steel (AISI 4140/4340), stainless steel (316/304), or titanium alloys. Surface treatments include black oxide coating, zinc plating, or electroless nickel for corrosion resistance and reduced friction.
Technical Parameters
  • Pitch 0.35mm-1.0mm
  • Length 10mm-100mm
  • Head Type Hex socket, slotted, or knurled
  • Thread Type Metric fine thread (M4-M12)
  • Torque Range 0.5-10 Nm
  • Surface Finish Ra 0.8μm max
  • Tolerance Class 4H/4h or better
Standards
ISO 4762, DIN 912, ISO 965-1

Frequently Asked Questions

What distinguishes a precision adjustment screw from standard screws?

Precision adjustment screws feature tighter tolerances (typically IT6 or better), finer thread pitches, specialized surface finishes, and controlled torque characteristics to enable accurate, repeatable adjustments without backlash or drift.

How often should precision adjustment screws be recalibrated?

Recalibration frequency depends on operating conditions, but typically every 6-12 months for continuous use, or after 10,000 adjustment cycles. Regular torque verification is recommended monthly.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
