Situo Hardware is a professional custom factory specializing in custom adjustable tool connecting pin shafts and CNC machined precision tooling connection locating pin mechanical accessories. We focus on non-standard CNC machined tooling parts for industrial automation jigs, precision fixtures, testing tools and mechanical equipment modules.
Core Product Advantages
Precision One-Piece CNC Machining
Entire pin shaft integrally formed in single clamping process, eliminating secondary processing deviation and mold tolerance errors. Strictly controlled straightness, roundness and concentricity ensure smooth burr-free surface and excellent batch consistency.
Flexible Adjustable Structure
Supports precise gap fine-tuning and stroke adjustment, perfectly adapting to assembly tolerance errors and space deviations. Eliminates need for multiple pin specifications, reducing inventory and tooling transformation costs.
Dual Connection & Positioning Functions
Integrates high-strength fastening connection and accurate limiting positioning. Achieves tight fitting and zero-shake locking after fine adjustment, ensuring precise alignment benchmark for frequent disassembly applications.
High-Quality Wear-Resistant Materials
Industrial-grade solid 304/316 stainless steel and high-hardness carbon steel. Stainless steel provides excellent rust and corrosion resistance; heat-treated carbon steel features high surface hardness and strong fatigue resistance.
Full Non-Standard Customization
Custom shaft diameter, length, adjustment stroke, stepped structure, locking holes and thread specifications. Supports rapid prototyping and large-scale OEM mass production according to customer requirements.
Strict Industrial-Grade QC System
All finished pins undergo concentricity testing, straightness calibration, adjustment smoothness testing, full-dimensional inspection and simulated assembly verification. Batch qualified rate over 99%.
Application Scenarios
Adjustable gap fine-tuning locating pins for automation tooling jigs
Stroke adjustment and precision limiting connecting pins for precision testing fixtures
Spacing adaptation and flexible fixing pin shafts for mechanical equipment module assembly
Non-standard alignment and error-tolerant assembly hardware for intelligent instrument tooling
Flexible adjustable connecting accessories for repeatedly debugged industrial tooling
Service & Production Capacity
Integrated production process covers raw material selection, one-piece CNC precision cutting, adjustable structure optimization, surface finishing and strict quality inspection. We support 3-5 days rapid prototyping, flexible small-batch customization and large-scale mass production with inspection reports and export-grade packaging for global delivery.

Frequently Asked Questions
What is an adjustable tool connecting pin shaft used for?
It is a high-precision CNC machined flexible tool accessory, mainly used for gap fine-tuning, stroke adjustment, connecting fixing and precision positioning of automation tooling, mechanical modules and testing fixtures.
What are the advantages of adjustable pins over standard fixed pins?
The adjustable structure supports on-site fine-tuning to adapt to assembly tolerance deviations, avoiding frequent replacement of different specification pins, with stronger compatibility and lower tooling maintenance costs.
Can you customize special adjustment stroke and pin size?
Yes, we fully customize shaft diameter, length, adjustment range, locking structure and mounting method according to customer drawings and actual tooling debugging requirements.
Are adjustable connecting pins durable for frequent use?
Adopting high-hardness wear-resistant materials and integral CNC machining, the pins resist abrasion and structural looseness after long-term repeated adjustment, maintaining stable positioning accuracy.
