Anti-Rotation Knurled Structure Knurled Hole Pin
,Multi-Functional Through-Hole Design Knurled Dowel Pin
,High Precision CNC Machined Locating Pin
Situo Hardware is a professional manufacturer specializing in knurled hole pins, knurled through-hole locating pins, anti-rotation knurled dowel pins and non-standard CNC machined knurled fasteners. Our products are widely used in automation equipment, tooling jigs, precision molds, instrument housings, mechanical transmission components and new energy wire harness limit structures.
This series of knurled hole dowel pins is made of high-quality stainless steel, carbon steel and alloy steel with precise CNC turning and milling processing. The outer knurled structure provides tight interference fit after press-fitting, realizing excellent anti-slip and anti-rotation positioning performance. The central through hole supports shaft penetration, wire threading, circlip installation and limit assembly, achieving multi-functional integration of positioning, fixing and secondary assembly. With high dimensional accuracy, good coaxiality and burr-free surface, the pins are firm after installation and highly adaptable for custom mechanical assembly.
Precision knurling with uniform texture ensures tight occlusion after press-fitting. It effectively prevents pin rotation and loosening under vibration and long-term operation, providing more stable positioning than ordinary smooth pins.
The central through hole allows shaft connection, wire harness routing, steel wire limiting and circlip fixing. It supports flexible assembly, disassembly and multi-structure combination, ideal for complex mechanical modules.
One-clamp forming ensures strict tolerance control of outer diameter, length, inner hole and knurl size. Excellent straightness and coaxiality guarantee smooth press-fitting and high batch consistency.
304/303 stainless steel for rust-proof and humid environments; carbon steel and alloy steel for high-hardness, wear-resistant and heavy-load working conditions. Heat treatment is available for higher rigidity.
Customizable outer diameter, total length, inner hole size, knurl length and head shape. Full knurl, half knurl and stepped knurl structures are available according to drawings and samples.
Passivation, blackening, zinc plating, nickel plating and polishing ensure anti-rust, anti-corrosion and smooth surface, suitable for complex industrial environments.
