Slotted Head Knurled Press-In Stud
Products Description
The Slotted Head Knurled Press-In Stud is a precision press-in fastener. Its core structure typically consists of the following parts:
Slotted Head
Knurled Section
Press-In Zone
Threaded Section
Pilot End
The product achieves a secure fixation through a stable interference fit between the knurled area and the mounting hole, making it suitable for applications requiring high-strength positioning and long-term stable assembly.
The slotted design improves installation convenience, making it suitable for some manual adjustment or maintenance situations, while also accommodating automated assembly needs.
Design Advantages
Optimized Knurling Pattern
Utilizing straight, diagonal, or diamond-shaped knurling, the depth and angle of the knurling are customized based on the hardness of the base material to achieve maximum friction and minimum stress concentration.
01
Flat Corner Transition between Head and Shaft
Reduces stress concentration, prevents cracking during pressing, and enhances shear resistance.
02
Guiding Chamfer Design
The precisely chamfered front end of the shaft facilitates centering and pressing, reducing the risk of assembly damage.
03
Optimized Slot Depth and Width
Ensures reliable engagement with standard flathead screwdrivers or automated equipment, preventing slippage.
04
Customization Flexibility
Supports modifications to head diameter, knurling length, thread specification, and overall length to meet specific positioning or heat dissipation requirements for Slotted Head Knurled Step Pin.
05
Deep Application Advantages: Solving Engineering Pain Points
The Ultimate Solution for Thin Plate Connections
Solves the problem of insufficient thread strength or inability to tap thin metal plates (low carbon steel, aluminum alloy, stainless steel).
Vibration Resistance and Loosening Prevention
The unique knurled interlocking structure maintains the axial stability of the fastener and the substrate even under continuous high-frequency vibration.
Simplified Assembly Process
Combined with automated press-fitting equipment, Slotted Knurled Locating Stud enables high-efficiency production, significantly reducing the time and cost of manual alignment, welding, and grinding.
Technical Features: Microfluid Dynamics of Interference Coordination
| Dual-Effect Knurling Array | Standard configuration features a composite knurling profile with straight lines (resisting axial pull-out) and cross-hatching (resisting radial torsion). Straight lines provide tear-like axial tensile resistance, while cross-hatching provides superior torsional resistance through multi-directional constraint. Together, they completely lock the Slotted Head Knurled Locating Stud's displacement in six degrees of freedom. |
| Stress-Relief Groove Design | Specific micro-discharge grooves are designed in the knurled area. When the substrate is extruded, the unplaced volume is redistributed along the grooves, not only reducing the peak thrust during extrusion and preventing substrate hole wall cracking, but also creating a "barb" effect in the rheologically modified substrate, significantly increasing pull-out resistance. |
| Strict tolerance zone allocation | The outer diameter of the Slotted Head Knurled Positioning Stud knurled part, the diameter of the guide part, and the bottom hole of the substrate form a golden interference ratio (usually controlled at 2%-5% of the diameter of the substrate hole, depending on the material), ensuring that the pressing force and holding force reach the optimal balance point. |
