Slotted Head Knurled Positioning Stud
Products Description
Slotted Head Knurled Positioning Studs are functional fasteners used for press-fit or semi-permanent positioning. Their core structure consists of three parts:
Slotted Head: Used for installation, removal, and initial positioning. It is compatible with standard flathead tools, facilitating manual or low-speed equipment operation.
Knurled Shank: Creates an interference fit through radial knurling, providing reliable mechanical locking with the mounting hole wall, achieving anti-rotation and high-stability positioning.
Plain/Threaded End: Can be used for functional connection, limiting, guiding, or securing subsequent components, depending on application requirements.
This structural design allows the stud to maintain axial and radial stability long-term after assembly without relying on additional anti-loosening measures.
Material Advantages: A Commitment to Quality at the Metallurgical Level
Ultimate Tempering of Alloy Steel
For standard models, we select high-quality medium-carbon steel or alloy steel (such as SCM435). Through strictly controlled quenching and tempering processes (tempering treatment), the material core achieves excellent toughness, while the surface possesses high hardness. This "hard outside, tough inside" metallographic structure ensures that the Slotted Knurled Press-In Pins are not easily broken under high tightening forces, and the threaded portion exhibits excellent wear resistance.
The Corrosion-Resistant Barrier of Stainless Steel
For humid or corrosive environments such as food machinery, medical devices, and marine engineering, we offer SUS304 or SUS316 stainless steel. Not only does the Slotted Head Knurled Locating Stud possess natural corrosion resistance, but passivation treatment further enhances its surface oxidation resistance, ensuring easy disassembly and no rusting even after long-term service.
Controllable material purity
All raw materials are sourced from top-tier steel mills and undergo rigorous compositional spectral analysis before entering the factory. Strict control over the content of harmful impurities such as sulfur and phosphorus eliminates the risk of brittle fracture caused by material inclusions at the source.
Detailed Showcase: A Microscopic Testimony of Craftsmanship
Chamfering of the Slot Edge
Carefully observe our slotted thread; you'll find extremely fine, rounded corners (R-angles) at the edges. This detail prevents the screwdriver from slipping during operation and protects the operator's hands from sharp burrs for the Slotted Head Knurled Step Pin.
Guiding Chamfer at the Thread End
The thread end is not abruptly cut off but rather machined with a long guiding chamfer. This makes the Slotted Knurled Locating Stud extremely smooth when screwed into the threaded hole, even automatically aligning itself and preventing parts from being scrapped due to "rough threads."
Smoothness of the Knurled Tooth Roots
Inferior knurling often leaves torn burrs at the tooth root. Our Slotted Knurled Locating Pins undergo a rigorous deburring process after knurling, resulting in clear, rounded tooth roots with a smooth feel, reflecting a high level of precision machining.
Bright Band on the Head Underside
The end face of the head that contacts the workpiece is precision ground, exhibiting a uniform metallic luster. This is not only aesthetically pleasing, but more importantly, it provides absolute planar contact, ensuring the vertical transmission of locking force.
