Slotted Head Knurled Locating Pin
Products Description
In high-reliability assembly systems, Slotted Head Knurled Locating Pins not only serve the function of "alignment" but also directly affect the repeatability, vibration resistance, and long-term stability of the overall structure. Traditional optical axis locating pins have significant limitations in terms of anti-loosening capability and ease of installation. However, slotted knurled locating pins, through a composite structural design, effectively address the following engineering pain points:
Risk of slippage or loosening during assembly
Micro-displacement issues under high-intensity conditions
Low efficiency of manual or automated installation
Inconvenient disassembly and maintenance
This product adopts a structural combination of "knurled interference + slotted drive," which ensures fastening stability while achieving more efficient assembly operations and greater maintenance flexibility.
Material Advantages: Balance of Chemical Composition and Physical Properties
High-Toughness Stainless Steel (SUS303/316L)
Designed specifically for medical devices and food processing machinery, offering excellent resistance to pitting corrosion and biocompatibility.
Tempered Alloy Steel (SCM435/12.9 grade)
Hardened to withstand extremely high shear stress and wear from repeated positioning for Slotted Head Knurled Locating Stud.
Environmentally Friendly Free-Machining Brass
Slotted Knurled Press-In Pin Designed for the electronics and communications industries, providing excellent electrical conductivity and processing stability, and fully compliant with the EU RoHS directive.
Main Functions: Multi-dimensional Capabilities Beyond Positioning
Precision Positioning
Serves as an assembly reference, ensuring consistent coordinate positions of workpieces, molds, or components during repeated installations. The knurled joint and interference fit of the hole eliminate radial clearance, achieving positioning repeatability within ±0.02mm.
01
Anti-rotation Locking
The interlocking structure between the knurled teeth and the hole wall prevents the Slotted Knurled Locating Stud from rotating during use, especially suitable when the pin also functions as a threaded support, guide rod, or rotation stop.
02
Reusable Installation and Removal
The slotted design allows for easy installation and removal of the Slotted Head Knurled Press-In Stud, meeting the needs of rapid mold changes, maintenance, and flexible production line adjustments, significantly reducing the overall lifecycle maintenance cost of the equipment.
03
Axial Positioning and Limiting
The head can serve as an axial limiting surface to control insertion depth; simultaneously, the bottom surface of the head can withstand a certain axial clamping force for securing thin plates or lightly loaded components.
04
Guiding and Centering
During the docking of large components, the Slotted Knurled Step Pin can be used as a temporary guide pin. Installing a few pins first guides the component to the center before completing other fastening operations.
05
Manufacturing Advantages and Production Processes
We employ an internationally leading composite process of precision cold heading, multi-station CNC rolling, and laser grooving to ensure the geometric accuracy and surface consistency of every Slotted Head Knurled Positioning Stud. Core processes include:
Precision wire cold heading – one-time forming of the head groove and guide end, eliminating secondary processing errors;
High-precision CNC knurling – micron-level control of knurling depth, angle, and coverage, resulting in uniform and discontinuous texture;
Laser precision grooving – groove width, depth, and symmetry far exceeding traditional milling, with burr-free edges;
Automatic deburring + 100% visual inspection + torque/insertion force sampling inspection – achieving zero-defect delivery.
Compared to traditional turning processes, this composite process offers higher material utilization, faster production cycles, and significantly improved surface integrity. Our intelligent manufacturing base is equipped with a fully automated sorting and packaging line, providing customers with a seamless transition from sample verification to large-scale mass production. We strictly adhere to both ISO9001 and IATF16949 standards to ensure high performance consistency across batches.
