Brass Adjustment Nut, Depth Control Knob Mechanical Fitting Part

Brass Adjustment Nut, Depth Control Knob Mechanical Fitting Part
Product Overview

This Brass Adjustment Nut is a precision mechanical fitting part integrated with depth control and positioning adjustment functions. Manufactured from high-quality solid brass material using CNC precision machining, the knob-style adjustment nut features smooth rotation, precise thread matching, and stable locking performance. It is commonly used for mechanical equipment depth setting, stroke positioning, gap adjustment, and fine tuning assembly, serving as a basic adjustable hardware component for automated machinery, instrument equipment, and industrial fixtures.

Product Features
  • Premium Solid Brass Material: Made from qualified industrial brass raw material with good structural toughness and natural oxidation resistance. Maintains stable surface condition in conventional working environments, resistant to rust and deformation during long-term repeated adjustment.
  • Precision CNC Machining: Integrated CNC turning processing ensures uniform size, regular outline, and smooth thread surface. Standard and consistent thread pitch enables steady rotation and fine feeding for accurate micro depth and stroke adjustment.
  • Knob Type Design: Humanized knob structure increases contact friction area for convenient manual rotation and adjustment. No auxiliary tools required for daily fine tuning and locking, with compact structure suitable for limited assembly positions.
  • Smooth Surface & Burr-Free Finish: All edges, threads, and contact surfaces are finely deburred and polished. Smooth surface without sharp edges or processing burrs ensures flexible rotation adjustment and prevents damage to matching parts.
Application Scenarios
  • Mechanical equipment depth positioning and fine adjustment
  • Industrial fixture and tooling stroke control fitting
  • Automation equipment gap tuning and locking parts
  • Precision instrument adjustable assembly components
  • Mechanical frame spacing and height adjustment hardware
