Lisle 15/16" Truck Cage Bolt Socket, Extra-Deep — 1/2" Drive, Heat-Treated Alloy Steel

The Lisle 49020 is an extra-deep 15/16" cage bolt socket designed to reach recessed fasteners on truck spring brakes, dump bodies, and heavy-duty chassis components.

Built for professional mechanics and fleet technicians, this socket offers the length and strength needed to engage 15/16" caging and mounting bolts that standard sockets can't reach. Forged from heat-treated alloy steel and sized for 1/2" drive tools, it accepts impact wrenches and hand ratchets alike. Its extra depth makes it especially useful on 30/36 spring brakes and MGM-style components found on Autocrat, CCC, and many garbage and dump trucks.

How does this socket reach bolts on deep or obstructed truck components?

The extra-deep design provides the extended reach required to slip over long studs, brake cams, and saddle clamp bolts without removing surrounding hardware. That reach trims time spent dismantling assemblies to access a single nut. It is shaped to clear common obstructions so you can work faster in confined areas.

• Extra-deep 15/16" opening for recessed nuts and caging bolts
• Clears long studs and U-bolts on headache racks and tanks
• Fits over S-cam bracket studs and spring brake components

Can I use the Lisle 49020 with power tools?

Yes — the socket is compatible with 1/2" drive hand ratchets and impact wrenches, making it versatile for both shop and roadside work. Its forged, heat-treated alloy steel construction withstands repeated torque from impact tools while maintaining shape and fit.

• 1/2" drive square recess fits standard ratchets and impact gun adapters
• Alloy steel forging resists deformation under torque
• Heat treatment improves durability for heavy-duty use

What heavy vehicle tasks is this socket best suited for?

This socket excels at removing or installing 15/16" nuts used in truck brake and body applications. It is commonly used on 30/36 spring brakes, MGM brake assemblies, and dump truck or garbage truck caging bolts where the nut sits deep on a stud.

• Works on 30/36 spring brake caging bolts and airline fittings
• Removes fuel tank saddle clamps and U-bolts on racks
• Services S-cam brackets and other deep-mounted chassis nuts

How durable is the Lisle 49020 for repeated fleet use?

Designed for professional environments, the socket's forged alloy steel body and heat-treated finish provide long service life even under heavy use. Proper tool-matching — using a 1/2" drive impact or high-quality ratchet — helps preserve the socket's geometry and extend its lifespan.

• Forged alloy construction for high strength and toughness
• Heat-treated for wear resistance and consistent fit
• Compatible with impact tools when used within recommended torque limits

Who is this for: the Lisle 49020 is aimed at fleet maintenance crews, mobile service techs, truck and trailer shops, and serious DIYers who work on heavy-duty commercial vehicles. If you frequently encounter recessed 15/16" nuts on spring brakes, dump-body hardware, fuel tank saddles, or S-cam assemblies, this extra-deep socket reduces disassembly time and improves access without resorting to improvised extensions.
