Product Description
Our Hex Male-Female Standoff Screws are precision-engineered spacers designed for reliable board-level stacking and spacing in electronic assemblies. The H4.75-M3x20+4 model features a hexagonal body for easy installation with a standard wrench, with male threads on one end (4mm long) and female threads on the other (16mm deep), enabling flexible and secure connections. Manufactured from A2-70 (304) Stainless Steel and finished with a blue-white zinc plating, they offer a cost-effective solution with good corrosion resistance for general-purpose indoor applications, making them a staple in electronics manufacturing.

- PCB Stacking: Creating multiple layers of printed circuit boards (PCBs) in servers, routers, and data storage equipment.
- Component Spacing: Providing precise space between boards and chassis for airflow, heat dissipation, and component clearance.
- Equipment Mounting: Securing modules, daughterboards, and drives within computers, industrial controls, and test instruments.
- Grounding: Establishing reliable electrical grounding paths between PCBs and metal enclosures.
- Consumer Electronics: Used in appliances, networking devices, and audio/video equipment.
- Tool Selection: Use a 3/16 inch (4.76mm) hex wrench to match the standoff's head size.
- Install Male Thread: Screw the 4mm male thread (M3) into a pre-tapped hole in the chassis or a base PCB. Tighten securely using the hex wrench, but avoid over-torquing to prevent damaging the threads.
- Stack Components: Place the board or component that needs to be spaced over the installed standoff.
- Secure Assembly: Insert a M3 machine screw (sold separately, max recommended length ~14mm to avoid bottoming out in the 16mm deep hole) through the component and into the female thread of the standoff. Tighten the screw to complete the assembly.
- Custom Configurations: We can customize the male and female thread lengths to suit your specific design and stack-up height requirements.
- More than 20 years of screw production experience and non-standard screw custom development experience, provide you with cost-effective screws, and help you solve the fastener supply chain.
- Precise production equipment. The company introduces all imported equipment from Taiwan to produce precision screws and hardware accessories for you. Provide free sample testing for compatibility verification.
- A complete management system, each batch of products that leave the factory undergoes multiple strict monitoring.
- Dedicated account management for seamless collaboration. System-supporting services guarantee you peace of mind.
