Discover more about the Threaded Standoffs range.
Threaded standoffs are precision-engineered components designed to create a fixed distance between two parts, typically within an assembly. Featuring machine-threaded ends in either male/male or male/female configurations, these standoffs offer secure fastening solutions for layered constructions.
Commonly found in enclosures, control panels and printed circuit board (PCB) mounting applications, threaded standoffs are an essential component in a wide array of engineering projects where space management and alignment are critical.
How Threaded Hex Standoffs Work
Threaded hex standoffs feature machine threads at both ends in a male-female or female-female configuration, allowing the male end to be screwed directly into components or panels providing a space at the female end for other assembly components to then be mounted on top with precision screws. This enables secure mounting of components at a set distance, maintaining structural integrity and allowing for easy disassembly.
In electronics, they are often used to secure a PCB above a mounting surface while maintaining a fixed height. Their hexagonal body enables easy installation with standard tooling such as a wrench. The precise metric machine threading ensures a reliable and vibration-resistant connection across other electronic components and assemblies.
Materials Threaded Hex Standoff Spacers Are Made From
Our threaded hex standoff spacers in this range are made from high-performance engineering metals and polymers, selected for their mechanical strength and insulating properties:
- Stainless Steel (A1, A2, A4): Offers excellent corrosion resistance and mechanical strength.
- PEEK: Provides high thermal stability and is ideal for chemically aggressive environments.
- POM with Nickel-Plated Brass Male Threaded Standoff: Combines the lightweight and insulation properties of POM with the thread strength of nickel-plated brass.
- RENY: A reinforced nylon polyamide offering superior dimensional stability and rigidity.
Sizes and Types of Threaded Hex Spacer Standoffs Available
Accu's range of threaded hex spacer standoffs are available in a variety of sizes to accommodate a range of engineering needs:
- Thread Sizes: M2 (2mm) and M36 (36mm).
- Standoff Lengths: From 4mm to 108mm.
- Types: Female-female and male-female threaded hex standoff configurations, compatible with machine thread assemblies.
FAQs
Q: What is the purpose of standoffs?
A: Threaded standoffs create space between components, offering mechanical support and electrical insulation, especially in electronics for items such as PCBs.
Q: What is the difference between a spacer and a standoff?
A: A spacer simply provides separation without threading, whereas a standoff includes internal or external threads for screw-in assembly reducing assembly steps in the process.
Q: How do you screw in standoffs?
A: Threaded hex standoffs can be installed using a spanner or nut driver, gripping the hexagonal body to ensure accurate torque and alignment. Additional components and fasteners can then be installed into the female threaded standoff end.
Q: What materials can hex standoff spacers be installed into?
A: Hex standoff spacers can be installed into a variety of materials including metals and plastics. While machine-threaded standoffs require pre-tapped holes, self-tapping threaded standoffs are suitable for softer materials such as plastics or light metals, eliminating the need for a pre-formed thread.
