Detailed description

Custom CNC Turned Knurled Threaded Locating Pin

Our Custom CNC Turned Knurled Threaded Locating Pin is a precision positioning fastening component integrated with anti-slip knurled head, external thread adjustment section and cone point centering tip, designed for manual operation and accurate locating assembly. As a professional CNC turning manufacturer based in Dongguan, we produce customized knurled threaded locating pins with ±0.01mm ultra-precise tolerance strictly following customers’ 2D & 3D engineering drawings. We support full OEM & ODM customization for total length, thread specification, knurling parameter and cone point angle. These knurled locating pins are widely used for fixture positioning, mold locating, equipment adjustment and precision assembly in automation, mold manufacturing and mechanical equipment fields.

Introduction to CNC Lathe Turning Technology

CNC lathe turning is one of the most precise and efficient manufacturing methods for rotational metal components used in industrial automation and precision equipment. Using programmable multi‑axis turning centers, metal bars are processed through continuous cutting, facing, grooving, threading and boring with computer‑controlled accuracy.
Compared with manual machining and conventional milling, precision CNC turning achieves stable dimensional tolerance down to ±0.01mm, smooth surface quality and outstanding consistency during mass production. It is widely applied to fabricate pins, shafts, bushings, connectors and threaded parts for mold, electronics, medical, automotive and automation machinery.
Equipped with secondary milling and cutting capacity, CNC turning supports complex customized profiles including stepped cylinders, grooved structures and multi‑sided profiles, satisfying diversified precision positioning component demands for industrial equipment.

Product Definition & Industrial Value

Knurled threaded locating pin is a manual adjustable positioning fitting integrating anti-slip knurled head, threaded adjustment section and conical positioning tip. The knurled head provides sufficient friction for hand-tight operation without extra tools, the external thread realizes precise stroke adjustment and reliable locking, and the cone point ensures fast and accurate centering positioning. It solves common industry pain points such as inconvenient tool-assisted adjustment in narrow space, low positioning accuracy and easy slipping during repeated operation. The integrated structure ensures stable positioning performance and convenient adjustment, effectively improving assembly efficiency and positioning accuracy for fixtures, molds and precision equipment.

Our Product Service

We provide one-stop custom CNC turning service for knurled threaded locating pins for global automation equipment, mold and fixture manufacturers. Our product scope covers custom locating pins, positioning pins, adjustment pins and other non-standard precision turned hardware. We complete full turning, knurling forming, external thread cutting, cone point processing and deburring strictly based on customer engineering drawings. Value-added services include diversified surface treatment, full-dimension inspection, prototype sampling and large-batch OEM production.

5 Core Advantages

Tool-free operation with anti-slip knurled head

The precision CNC-formed knurled head features uniform tooth profile and moderate surface friction, supporting direct hand tightening and stepless adjustment without extra wrenches or screwdrivers. It is especially suitable for frequent adjustment scenarios and narrow assembly spaces, greatly improving operation convenience and on-site assembly efficiency.

High-precision cone point centering design

The conical tip is machined with high precision, which can realize fast self-centering and accurate positioning when matching with the corresponding hole, effectively reducing manual alignment deviation and ensuring consistent positioning accuracy for each assembly, suitable for high-precision fixture and mold positioning scenarios.

Stable thread adjustment and locking performance

The external thread is processed by one-time clamping with accurate pitch and standard fit tolerance, which can realize fine adjustment of positioning stroke and reliable locking after positioning. It maintains stable fit performance under long-term vibration and repeated disassembly, avoiding loosening and positioning displacement.

Diversified material and surface treatment options

Optional materials include carbon steel, stainless steel, brass and aluminum alloy to meet different requirements of strength, corrosion resistance and weight. Surface treatments such as zinc plating and nickel plating further enhance anti-rust and wear resistance, effectively extending the service life of the pin.

Full-parameter drawing-based customization

All key parameters including total length, thread standard, knurling specification and cone point angle can be fully adjusted according to your 2D/3D drawings or physical samples. We accept both small-batch prototype verification orders for new product development and large-volume mass production orders for formal projects.

OEM Custom Service Range

We provide comprehensive customized solutions for custom knurled threaded locating pins and all kinds of precision CNC turned components. Available materials include carbon steel, SUS304/SUS316 stainless steel, C36000 brass and 6061‑T6 aluminum alloy, with sufficient bar stock to match different strength, corrosion resistance and weight requirements.
Our custom product range includes locating pins, connecting shafts, bushings, threaded fittings and other rotational precision machined parts. Selectable surface treatments: natural machined finish, zinc plating, nickel plating, passivation, black oxide and anodizing.
We can supply single parts or matched hardware kits according to assembly needs. Custom machining will be developed based on your drawings or samples. Small batch prototype testing is available before formal mass production.

Typical Application Scenarios

Our Custom CNC Turned Knurled Threaded Locating Pin is widely used in fixture precise positioning assembly, mold centering locating fitting, automation equipment adjustment positioning, mechanical assembly centering connection, jig quick locating component and industrial hardware adjustable positioning assembly.

FAQ 3

Q: Can I get trial samples before mass production? How long is the sample lead time?
A: Trial samples are available for all customized turning orders. The sample production cycle is 3–7 working days after drawing confirmation. After you test and confirm the sample quality and dimensions, we will arrange mass production. Small batch trial orders are also acceptable if you do not need large volume at first.

FAQ 4

Q: What surface finishing options do you provide for CNC turned metal parts?
A: We offer multiple surface treatments to meet anti-rust, anti-corrosion, wear resistance and appearance demands: passivation, electropolishing, zinc plating, nickel plating, black oxide, powder coating, anodizing for aluminum, sandblasting and polishing. If your products are exported to Europe, we can provide surface treatment that complies with RoHS and REACH standards.

FAQ 5

Q: How do you control the dimensional tolerance of precision CNC turned parts?
A: Our standard tolerance for general turned parts is ±0.01mm, and ultra-precision components can achieve ±0.005mm with grinding processes. We carry out strict three-step quality inspection: IQC for raw material incoming check, IPQC for in-process production monitoring, and FQC full dimension testing before shipment. We provide inspection reports and accept third-party quality inspection as requested.
