Wabco 16500023 Hollow Screw

Description

The Hollow Screw Fag A0023 by Wabco is a critical component used within the brake drum assembly of mechanical brake systems. This screw is designed to securely fasten brake components, ensuring reliable and efficient braking performance. Manufactured to OE specification, this part delivers a precise fit and consistent functionality, contributing to enhanced safety and durability within the braking system. Its design and materials contribute to corrosion resistance and long-term reliability.

Key Features & Benefits

These screws actually hold the brake drum onto the wheel hub. They aren’t your typical fasteners, though. They’re designed with a hollow center, and they shear—basically, they’re meant to break at a specific point—if the drum gets stuck or overheats. It’s a safety feature. They keep everything together under normal driving, but they act like a shield, protecting more expensive parts from damage if something goes wrong with the brakes. They’re a pretty specific part, only used where you have a brake drum system, of course. They connect the drum directly to the wheel, and they have to withstand a lot of heat and stress during braking. They’re not something you’d find on every vehicle, primarily older cars and some trucks still use drum brakes.

Symptoms, Risks & Replacements

Well, if these screws fail and aren’t replaced, the brake drum can become loose, which is obviously a safety issue. You’ll notice if one’s gone missing, usually because of wobbling or rattling when you brake. Ignoring it can lead to more serious damage to the wheel hub or other brake components. They’re a relatively inexpensive part, and a pretty crucial one to keep your brakes working safely. You can find them easily enough, even online at places like Fixparts Online, and it’s definitely something a good mechanic would check during a brake service.
