Buyer's guide to PCB hardware
Which PCB hardware solution best suits your application, while also being cost-effective?
When buying PCB hardware, there are lots of factors to take into consideration. Costs, managing space and heat, ease of accessibility and conductivity in your application are all important when building electrical solutions.
When it comes to circuit board hardware, material and mounting type are key. We strongly recommend that you try before you buy – request free samples so that your team can ensure they have the perfect solution for the application. They can also download free CADs.
This guide is designed to give buyers an introduction. For expert advice, we’re always happy to help. We can also help with our vast range of PCB standoffs and spacers, PCB support pillars, PCB card guides and LED mounts and holders.

How to choose the right PCB mounting type?
Choosing the right spacing component as part of your PCB hardware design can be a challenge. Many considerations such as board substrate, application and material are key elements in the decision-making process. However, one of the most important choices you can make is mounting type. Here are some examples of circuit board mounting types:
Threaded PCB hardware
- Standard: Held in position with the use of a nut to give a very secure fixing that can be released and re-tightened.
- Undercut: Provides a more secure connection by being fixed into the thread.
- Self-tapping: No closing washers or nuts necessary due to self-tapping thread.
Snap fit PCB hardware
Quickly pushes into a panel or chassis hole, giving a strong but efficient mounting that saves you time when undergoing installation.
Different types available: edge lock, bayonet and fir tree.
Snap lock PCB hardware
Pushes into a panel or chassis hole, giving a secure but easily releasable fix.
Press fit/blind hole PCB hardware
Fins hold securely to a range of binding holes with a painted style that drives easily into applications with space restrictions.
Adhesive base PCB hardware
Adhesive tape eliminates the need for a mounting hole, providing time and space efficiencies.
