The world's leading manufacturer of precision hardware products
Has decades of rich experience and advanced equipment
We specialize in the design and manufacture of Custom Made Stainless Steel Pins tailored to your exact specifications. Whether you need a simple dowel for alignment, a complex grooved pin for retaining mechanisms, or a precision shaft for a medical device, our CNC machining capabilities deliver unparalleled accuracy. Crafted from high-grade stainless steel, these pins are engineered to provide superior strength, corrosion resistance, and dimensional stability in the most demanding environments.
We are not limited to standard stock sizes. We can produce virtually any pin configuration based on your engineering drawings or reverse-engineered samples.
Dowel Pins: Precision-ground for exact alignment and location of mating parts in machinery, molds, and fixtures .
Grooved Pins: Featuring pressed-in grooves that create a secure, press-fit locking action, eliminating the need for secondary retaining methods .
Spring Pins (Roll Pins): Slotted and coiled designs that compress during insertion, providing vibration resistance and high shear strength .
Clevis Pins: Headed pins designed for use with a cotter pin or clip in linkage applications, such as hydraulics and farm equipment .
Pivot & Hinge Pins: Custom lengths and diameters for heavy-duty pivoting applications in construction, automotive, and industrial machinery .
Shoulder Pins & Screws: Precision-machined with a shouldered head to act as a stop, spacer, or pivot point .
Lock Pins & Detent Pins: Custom pins with spring-loaded balls for quick-release and positive locking applications .
Choosing stainless steel for your custom pins ensures long-term reliability and performance.
Superior Corrosion Resistance: Ideal for applications exposed to moisture, chemicals, or sterilisation processes. Grades like 316 stainless offer exceptional resistance to pitting and crevice corrosion in marine and medical environments .
High Tensile Strength: Stainless steel pins withstand heavy loads, impact, and shear forces without deforming, ensuring structural integrity in critical assemblies .
Temperature Resistance: Maintains mechanical properties across a wide range of temperatures, from cryogenic conditions to high-heat industrial processes .
Non-Magnetic Options: Austenitic grades such as 304 and 316 are essentially non-magnetic, making them suitable for sensitive electronic and medical imaging equipment .
Hygienic & Easy to Clean: The non-porous surface prevents bacterial growth and simplifies cleaning, essential for food processing and pharmaceutical applications .
Every custom pin is manufactured using precision CNC machining and finishing techniques to meet your exact requirements.
Material Selection & Certification: We source certified stainless steel bar stock in grades including 303, 304, 316, 17-4 PH, and 410. Material Test Reports (MTRs) ensure full traceability .
CNC Turning & Grinding: Our CNC Swiss lathes and turning centers machine the pins to precise diameters and lengths.
For Standard Tolerances: High-speed CNC turning achieves tight dimensional accuracy (typically ±0.01mm to ±0.05mm).
For Critical Fit Applications: Centerless grinding is available to achieve ultra-precise diameters with tolerances up to ±0.0025mm and mirror-like surface finishes .
Feature Creation (Grooves, Holes & Threads): Using live tooling and secondary machining operations, we add complex features:
Grooving: Creating precise undercuts, retaining ring grooves, or lubrication channels.
Cross-Drilling & Slotting: Drilling holes for cotter pins, or milling flat surfaces and drive slots.
Threading: Cutting internal or external threads for threaded pin applications.
End Treatment & Chamfering: All pins are carefully deburred and chamfered to ensure safe handling, ease of assembly, and to prevent damage to mating components .
Surface Finishing: We offer a variety of finishes to enhance performance and appearance:
Passivation: Chemically cleans the surface and enhances the natural corrosion resistance of the stainless steel.
Electropolishing: Provides a smooth, bright, and sterile finish while improving corrosion resistance.
Mechanical Polishing: For a decorative, high-luster appearance.
Custom stainless steel pins are the "unsung heroes" of mechanical assemblies, found in virtually every industry:
Medical & Surgical: Bone pins, surgical guide pins, dental implant abutments, and instrument pivot pins requiring biocompatibility and sterilizability . (Grade: 316L, 17-4 PH)
Aerospace & Defense: Locking pins for landing gear, hinge pins for flight controls, and alignment dowels for avionic chassis . (Grade: 15-5 PH, 304)
Marine & Offshore: Clevis pins for rigging, shackle pins, and corrosion-resistant fasteners for deck hardware . (Grade: 316)
Automotive & Motorsport: Gearbox selector pins, brake caliper guide pins, suspension pivot pins, and engine dowels . (Grade: 303, 17-4 PH)
Industrial Machinery: Locating dowels for die sets, pivot pins for linkages, and conveyor system retaining pins .
Food Processing: Quick-release pins for wash-down equipment and hinge pins for sanitary conveyors . (Grade: 316)
While standard off-the-shelf pins are readily available, custom manufacturing offers distinct advantages:
Perfect Fit: Eliminates the need for modifying your assembly to accommodate a standard part.
Optimized Performance: Allows you to specify the exact material grade, hardness, and surface finish required for your specific load and environmental conditions.
Consolidation of Features: A single custom pin can replace an assembly of multiple standard parts, reducing complexity and inventory costs (e.g., a pin with an integrated head and groove).
Design Flexibility: We can produce pins in non-standard diameters, unusual lengths, or with unique features (like special undercuts or drive features) that are simply not available off the shelf.
Precision Inspection: Parts are verified using micrometers, optical comparators, and CMMs.
Hardness Testing: Ensuring the pin meets required strength specifications.
100% Dimensional Checks: Available for critical features on high-volume orders.
