Adjustment Nut/Spacer Component – Machinery and Equipment Manufacturing

Component Specifications

Definition

A threaded nut or spacer component used in spring assemblies to fine-tune spring tension, compression, or positioning. It enables precise adjustment of spring force characteristics and maintains proper alignment between spring and mating components through controlled axial movement along threaded interfaces.

Working Principle

Operates through threaded engagement with mating components, allowing controlled axial displacement when rotated. The nut/spacer creates or relieves spring preload by changing the effective spring length, while maintaining structural integrity through proper thread contact and load distribution.

Materials

Typically manufactured from carbon steel (AISI 1018/1045), alloy steel (AISI 4140), or stainless steel (304/316). May include surface treatments: zinc plating, black oxide, or phosphate coating for corrosion resistance. Hardness range: 25-45 HRC for steel variants.

Technical Parameters

Thread Type Metric (M6-M20) or Imperial (1/4"-3/4")
Thread Pitch Standard coarse or fine pitch
Load Capacity 500-5000 N
Inner Diameter Thread dependent
Outer Diameter 10-40 mm
Height/Thickness 5-30 mm
Temperature Range -40°C to 120°C

Standards

ISO 4032, ISO 8673, DIN 934, DIN 439

Frequently Asked Questions

What is the primary function of an adjustment nut in spring assemblies?

The primary function is to provide precise control over spring tension and position by allowing fine adjustment through threaded movement, ensuring optimal spring performance and system calibration.

How do I select the right material for an adjustment nut/spacer?

Select based on application requirements: carbon steel for general use, alloy steel for high strength, stainless steel for corrosion resistance, and consider surface treatments for environmental protection.

Can adjustment nuts be reused after initial installation?

Yes, but inspect for thread wear, deformation, or corrosion. Re-torque to specified values and replace if signs of damage or excessive wear are present.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
