Hexagon Standoff Screw
Products Description
Our Hexagon Standoff Screws feature a one-piece or modular precision-machined structure. One end has an internal thread (female), and the other an external thread (male), with the central hexagonal body providing support height and operating torque. This design effectively solves the problems of insufficient torque, difficult alignment, and inaccurate height control associated with traditional cylindrical isolation posts, ensuring stability and consistency in multi-layered assembly.
Key Product Features:
Easy Hexagonal Operation: The hexagonal shape facilitates the application of uniform torque using wrenches or socket tools, improving installation efficiency and tightening reliability.
Precise Spacing Control: Standard or customized heights ensure accurate board spacing, maintaining circuit board flatness and heat dissipation channels.
Compatible Male and Female Threads: One stud can be used for multiple purposes, enabling stacked assembly and simplifying multi-layered connection processes.
Electrical Isolation Performance: Surface treatment provides a choice of good insulation or conductivity to meet different circuit safety requirements.
Application Advantages: Empowering High-Density Integrated 3D Spatial Solutions
| 5G Base Stations and AI Server Clusters | In heterogeneous computing boards driven by massive data flows, high-power chips require huge heat sinks. Brass isolation pillars not only precisely lock the Z-axis gap between the heat sink and the PCB, preventing PCB bending and deformation, but also construct a low-thermal-resistance heat dissipation bypass, quickly dissipating localized high temperatures, serving as the spatial and thermal support for ensuring stable computing power operation. |
| New Energy Vehicle Electric Drives and BMS | In the violently vibrating chassis and high-voltage control boxes, stainless steel brass isolation pillars withstand the enormous clamping force of IGBT modules and the continuous impact of vehicle movement. Their high yield strength and anti-loosening design ensure the absolute safety of high-voltage electrical clearances, eliminating the risk of a sudden drop in creepage distance due to vibration. |
| Avionics and Radar RF Compartment | In airborne equipment requiring extreme lightweighting and electromagnetic shielding, the aluminum alloy isolation column undergoes hard anodizing treatment, which not only achieves extreme weight reduction of the structure but also forms an equipotential connection of the conductive anodized surface with the fuselage, blocking the intrusion of external electromagnetic pulses and the leakage of internal radio frequency. |

Thread Start Chamfer
The first 1-2 threads of the male thread are chamfered to eliminate incomplete threads, facilitating quick nut insertion and reducing jamming on automated assembly lines.
Hexagonal Edge Rounding
All hexagonal edges are slightly chamfered or rounded to prevent scratching of the wiring harness or operator's fingers during assembly, while also improving plating adhesion for the Male-Female Hex Spacer.
Internal Thread Orifice Chamfer
A C0.2~C0.5 chamfer is added at the female end inlet to guide the Hex Male-Female Standoff smoothly and prevent thread damage due to misalignment.
End Face Marking
Material codes (e.g., "Br" for brass, "SS" for stainless steel) or size specifications can be stamped on the hexagonal end faces for easy on-site identification and error prevention.
Material Advantages | Clear Division of Labor Between Metals and Plastics
Brass (H59/H62)
The most classic material for hexagonal bracket screws. Brass has good conductivity, corrosion resistance, and machinability. It can be nickel-plated or tin-plated to further improve weather resistance and solderability. Widely used in power supplies, amplifiers, and industrial control equipment where conductive grounding is required.
01
Free-cutting steel (12L14/1215)
Higher strength than brass, lower cost, suitable for support structures bearing heavy mechanical loads. Zinc- or nickel-plated surfaces provide good rust prevention, suitable for non-corrosive environments inside chassis.
02
Stainless steel (SUS303/SUS304)
Used in outdoor, humid, chemical, or medical equipment. Stainless steel has high strength and strong corrosion resistance, and can be used for a long time without additional plating. For special applications requiring non-magnetic properties (such as MRI equipment), non-magnetic stainless steel can be selected.
03
Aluminum alloys (6061/6063)
The preferred choice for lightweight applications, suitable for aerospace, portable devices, or weight-sensitive applications. Aluminum alloy surfaces can be anodized to obtain different colors and insulating layers.
