Mounting Tabs Weld-On 4pk 5/8in Hole

The Mounting Tabs Weld-On 4pk 5/8in Hole from Allstar Performance is an essential fastening solution for custom automotive fabrication, engine builds, and chassis modifications. These weld-on tabs serve as anchor points for brackets, accessories, and support structures throughout your vehicle's frame and powertrain. Whether you're building a competition engine, fabricating custom motor mounts, or installing aftermarket components, reliable mounting infrastructure is foundational to a secure, professional installation that will endure vibration and lateral stress over thousands of miles.

Each tab in this four-pack features a 5/8-inch hole diameter, providing a standardized bolt pattern compatible with common fastener sizes across automotive applications. The weld-on design eliminates the need for threaded inserts or complex machining, allowing you to position these tabs exactly where you need them and fuse them permanently to steel substrates using standard MIG or stick welding equipment. Constructed from quality steel, these tabs are engineered to distribute loads evenly and resist fatigue failure—critical when mounting heavy components like alternators, power steering pumps, superchargers, or custom exhaust systems that generate dynamic forces during operation.

Fabricators, engine builders, and automotive enthusiasts rely on Allstar Performance mounting tabs to create clean, durable attachment points that simplify assembly and improve overall build quality. The compact dimensions and minimal weight make these tabs ideal for weight-conscious builds while maintaining structural integrity. Installation is straightforward: position the tab on your workpiece, tack weld, verify alignment, then complete the final weld bead for a permanent bond. At 0.12 lbs per four-pack, you'll have redundant tabs for your current project and spares for future modifications.
