Situo Hardware specializes in custom double-end hole adjustment shafts and CNC machined dual bore adjustable locating shaft mechanical hardware parts. Our precision components are designed for industrial automation, tooling jigs, inspection equipment, intelligent modules, and mechanical transmission assemblies.
Product Overview
Our double-end hole adjustment shafts are integrally CNC turn-mill machined from high-strength solid bar stock including 45# steel, 40Cr alloy steel, and 304/316 stainless steel. Precision through-holes are machined on both shaft ends to work with pins, circlips, and link assemblies for distance adjustment, angle fine-tuning, and position locking.
Core Advantages
Multiple Industrial-Grade Material Options
Premium solid bar stock including quenched & tempered 45# steel for hardness and wear-resistance, 40Cr alloy steel for toughness and fatigue resistance, and 304/316 stainless steel for corrosion resistance in humid environments.
High-Precision Dual-End Bore Machining
Single clamping setup eliminates concentricity errors, ensuring excellent alignment and smooth operation without pin jamming or assembly interference.
Integrated CNC Precision Machining
Complete one-piece machining with dimensional tolerances controlled within ±0.005mm to ±0.05mm, ensuring high batch consistency and interchangeability.
High Structural Strength & Vibration Resistance
Solid one-piece cutting structure with heat treatment provides excellent compression-resistance and bending-resistance, preventing deformation under adjustment impact and equipment vibration.
Comprehensive Customization Service
Full customization of shaft diameter, length, dual-end bore size, hole spacing, stepped profiles, circlip grooves, threads, and special-shape configurations based on customer requirements.
Strict Quality Control
Complete inspection process including dimensional verification, coaxiality calibration, hardness testing, and simulated adjustment tests with batch qualified rate exceeding 99%.

Frequently Asked Questions
What is a double-end hole adjustment shaft used for?
It is a precision machined shaft with through-holes on both ends, used for hinging, distance adjustment, angle fine-tuning, and position locking on automation jigs, inspection fixtures, and mechanical linkages.
Which materials are suitable for double-end hole adjustment shafts?
45# steel (quenched for heavy-load wear-resistance), 40Cr alloy steel (high-impact fatigue-resistant), and 304/316 stainless steel (corrosion-resistant for humid environments).
Can you customize special-size double-end hole adjustment shafts?
Yes. We customize shaft diameter, length, dual-end bore size, hole spacing, steps, grooves, and threads according to drawings or samples.
Why is coaxiality important for double-end hole adjustment shafts?
Good coaxiality of dual-end holes ensures smooth pin fitting and free adjustment without jamming, avoiding linkage stuck or abnormal wear in adjustment mechanisms.
