fasteners

Fasteners provide the mechanical backbone for electronic assemblies. They secure boards, panels, and enclosures to keep components aligned and protected. In this category, you'll find ball and spring plungers, hook-and-loop fasteners, inserts, mechanical pins, nuts, retaining and snap rings, rivets, screws, studs, and washers used in electronic equipment. These fasteners help manage vibration, thermal cycling, and service access in industrial and commercial systems. With U.S.-based inventory, reliable stock, and fast shipping, Online Components helps purchasing and engineering teams move from design to build without delays.

How to Choose the Right Fasteners

Choosing the right fasteners starts with how the joint will be used: panel thickness, hole size, and the forces it sees. Screws, nuts, and washers work well for serviceable joints that may need to be opened for inspection or upgrades. Rivets and studs are better for permanent connections. Inserts are useful when you need durable threads in softer materials, and mechanical pins provide accurate alignment, keeping boards and brackets in place so connectors stay where they belong. For designs that require frequent access, ball-and-spring plungers and hook-and-loop fasteners allow tool-free engagement and release, speeding assembly and maintenance.

Popular Applications for Fasteners

Fasteners are used wherever assemblies must be mounted, aligned, or protected. In control panels and enclosures, screws, nuts, washers, rivets, and retaining rings secure doors, backplates, and subassemblies, keeping components in place even when equipment is moved or serviced.

At the board and module levels, inserts, studs, and mechanical pins keep boards, heat sinks, and user-interface assemblies accurately in place. This helps maintain connector engagement and reduces stress on solder joints. Ball-and-spring plungers and hook-and-loop fasteners work well for access panels, removable covers, sensor modules, and cable management, where technicians need quick ways to secure and release parts.

Customer service and online ordering support both prototype builds and production programs.

Fasteners: What You Need to Know

What are fasteners in an electronic assembly?

Fasteners are mechanical hardware (screws, nuts, washers, rivets, studs, inserts, mechanical pins, and similar components) that secure boards, panels, and enclosures.

How do I decide between screws and more permanent fasteners?

Use screws with matching nuts and washers when a joint must open for inspection or upgrades. Choose rivets or studs for a permanent connection.

Why are inserts and mechanical pins important in electronics?

Inserts provide durable threaded mounting points in softer materials. Mechanical pins keep boards and brackets properly aligned, ensuring that connectors and displays line up reliably.

What role do washers and retaining or snap rings play?

Washers distribute load, protect surfaces, and help control torque. Retaining and snap rings hold components in place on shafts or in housings.

When should I use hook-and-loop fasteners or ball-and-spring plungers?

Hook-and-loop fasteners work well for modules, cable bundles, or covers. Ball-and-spring plungers provide repeatable detent positioning without tools.
