Description
A railway frog is the point in a turnout where one rail crosses another. Heavy bolts hold it together, and traffic hammers those bolts every day. The Snap-on PTQ8-FROG frog nut tool lets a PTQ8 pneumatic torque wrench reach and tighten those frog nuts under control.
What the Snap-on PTQ8-FROG frog nut tool is
Snap-on’s PTQ series brochure calls it a railroad socket for the PTQ8 when torquing frog nuts. The same brochure lists it in the reaction arm kit table as the Frog Nut Tool, with a tool length of 8.23 in. It also notes that the torque wrench and socket come separately. So plan the PTQ8, the frog tool and any socket as separate lines in your quote.
The PTQ8 behind it
| Drive | 1-1/2 in |
|---|---|
| Torque range | 1,300-8,500 ft-lb (1,763-11,524 N·m) |
| Accuracy | ±5%, set by input air pressure |
| Safety | Paddle that needs both hands on the tool |
Snap-on also describes a dual-speed gearbox, with a fast rundown gear and a slow torque gear. As a result, the PTQ8 spins a frog nut down quickly, then finishes it with control.
Why a dedicated frog tool helps
Track hardware sits low, between rails and ties, with little room for a standard reaction arm. A tool built for the frog lets the PTQ8 work in that space. In addition, a pneumatic wrench spares crews the hard pulls that big hand wrenches demand. Snap-on also notes far less vibration than an impact wrench, which matters on long night shifts.
Air supply and care
Run the PTQ8 through Snap-on’s PTQFRL filter-regulator unit, which comes with hoses, couplings and gauges. Then keep the frog tool free of ballast dust and grease, and check it for cracks after each job. Snap-on also suggests an annual calibration check for the wrench.
