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

The Lisle 49020 is an extra-deep 15/16" socket engineered to reach and release cage bolts on heavy-truck spring brakes, dump bodies, and other deep-recess fasteners.

If you work on garbage trucks, dump trucks, or heavy equipment with caged bolts—especially 30/36 spring brake assemblies like Autocrat and CCC styles or MGM brake systems—you need a socket that gets deep without sacrificing strength. The Lisle 49020 is forged from alloy steel, heat-treated for durability, and long enough to access recessed 15/16" nuts used on spring brake cages, S-Cam brackets, U-bolts, and more. It fits a 1/2" drive and is rated for use with an impact wrench, providing both hand-tool versatility and power-tool readiness.

Will this socket reach the cage bolts on common truck spring brakes?

Yes. The extra-deep length is designed to access the long threaded studs and cage nuts found on many 30/36 spring brake assemblies, including prevalent Autocrat and CCC configurations. Its internal depth clears the stud while engaging the nut fully, reducing the risk of rounding.

• Extra-deep 15/16" profile for recessed nuts
• Compatible with 30/36 spring brakes and MGM brake hardware
• Full engagement reduces slippage and fastener damage

Can I use the socket with an impact wrench or only by hand?

The Lisle 49020 accepts a 1/2" drive and is suitable for both hand-ratchet work and impact tools. Its forged alloy steel construction and heat treatment give it the toughness required for impact use, while the drive size fits standard impact adapters and breakers.

• 1/2" drive compatibility for sockets and impact tools
• Forged alloy steel withstands impact torque
• Heat-treated for improved wear resistance

What other applications will this 15/16" extra-deep socket handle?

Beyond spring brake cage bolts, the deep 15/16" socket is versatile for any recessed 15/16" nut or bolt that standard sockets can't reach. Common secondary uses include removing fuel tank saddle clamps, headache rack U-bolts, and caging bolts on S-Cam brackets.

• Fuel tank saddle clamp removal in deep pockets
• U-bolts on headache racks and chassis components
• S-Cam bracket caging bolts and similar deep fasteners

How does the construction affect long-term performance?

Material and heat treatment directly influence a tool's durability; this socket is forged from alloy steel and heat-treated to resist deformation and wear. That combination helps the socket maintain its fit and torque tolerance under repeated heavy use, lowering the chance of rounding nuts or thread damage.

• Forged alloy steel for high strength
• Heat-treated to improve hardness and longevity
• Design intended to hold up under impact and heavy loads

Who is this for: The Lisle 49020 is built for mechanics, fleet technicians, and body-shop professionals who service heavy trucks, refuse vehicles, and trailers. If you frequently remove or install caged spring-brake nuts, fuel tank clamps, U-bolts, or recessed S-Cam fasteners, this extra-deep 15/16" socket gives the reach, strength, and drive compatibility you need for reliable, repeatable removal and installation.
