Custom CNC Knurled Screw & Precision Pin Shaft
Stainless Steel Knurl Fastener Precision Locating Pin Mechanical Hardware Parts

Custom Stainless Steel Square Non-Standard Parts, CNC Machined Special-Shaped Irregular Mechanical Hardware Components

Product Overview

Situo Hardware is a professional factory specializing in custom CNC knurled screws and precision pin shafts, stainless steel knurl fasteners and precision locating pin mechanical parts. All products are manufactured by pure CNC machining process without stamping, die-casting or secondary splicing.

The knurled screws feature uniformly cut anti-slip knurl patterns for stable fastening and anti-loosening performance; the matching precision pin shafts are finely turned and ground with high coaxiality and accurate dimensional tolerance. Combining anti-slip fastening, precise positioning and limit guiding functions in one set, our machined hardware effectively solves common problems of standard parts such as slipping, poor positioning accuracy, assembly looseness and burr defects.

Full non-standard custom machining is available for special knurl tooth profiles, screw specifications and pin shaft structures for precision mechanical assembly.

Core Product & Factory Advantages
Pure CNC Machining Process with Higher Precision

Different from traditional stamped and die-cast standard parts, all knurl textures, thread profiles and pin shaft structures are integrally formed by one-time CNC precision cutting. The machining process avoids structural deformation and mold tolerance errors, ensuring uniform tooth depth, complete thread shape and zero shaft eccentricity.

Precision Knurl Pattern for Anti-Slip & Anti-Loosening

The CNC precisely cut knurled structure features regular symmetrical tooth shapes, deep and uniform textures with burr-free edges. It greatly increases surface friction, effectively preventing slipping and idling during manual tightening and equipment locking.

High-Precision Machined Locating Pin Shaft

The matching positioning pin shaft adopts micron-level CNC turning and grinding technology. Strict tolerance control within ±0.005mm~±0.05mm ensures excellent straightness, roundness and coaxiality. The smooth shaft surface enables flexible insertion and tight fitting.

Multiple High-Quality Material Options

We provide 304/316 stainless steel and carbon steel for customized machining. Stainless steel features excellent rust and corrosion resistance, while heat-treated carbon steel offers high hardness and strong torsion resistance for various working conditions.

Full Non-Standard Custom Machining

Free from standard part limitations, we custom machine special pitch knurled screws, fine/coarse thread fasteners, stepped pin shafts, holed locating pins and special-shaped knurl parts according to customer specifications.

Strict Machining Quality Control System

All finished products undergo full-dimensional inspection, tooth profile calibration, thread gauge testing, coaxiality detection and simulated assembly testing before delivery, with a batch qualified rate over 99%.

Application Scenarios
  • Anti-slip fastening and high-precision positioning machined hardware for automation equipment
  • Anti-loosening knurled fasteners for tooling jigs and inspection fixtures assembly
  • Custom machined positioning components for precision molds and intelligent module assembly
  • Rust-proof wear-resistant fastening and locating parts for instruments and dust-free equipment
  • High-frequency disassembly and vibration-resistant anti-slip mechanical hardware fittings

Frequently Asked Questions
What are CNC knurled screws used for?

CNC machined knurled screws are anti-slip and anti-loosening fasteners, widely used for stable locking and fastening of automation tooling, precision equipment and mechanical modules.

What is the advantage of CNC machined pin shafts?

One-piece precision machining ensures ultra-high coaxiality and dimensional accuracy, providing zero-deviation repeated positioning performance, which is more stable and durable than stamped standard pins.

Can you customize special knurl patterns and pin sizes?

Yes, we fully customize knurl tooth pitch, thread specification, pin diameter, length, stepped and holed structures according to customer drawings and samples.

Why choose CNC machined knurl fasteners instead of standard parts?

Pure CNC machining achieves higher precision, uniform anti-slip texture and better structural stability, solving slipping, burrs and low consistency problems of traditional stamped standard fasteners.
