定义
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.
工作原理
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.
材料
Typically made from alloy steel (AISI 4140/4340)stainless steel (316/304)or titanium alloys. Surface treatments include black oxide coatingzinc platingor electroless nickel for corrosion resistance and reduced friction.
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
标准
ISO 4762DIN 912ISO 965-1

常见问题

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.
