Description
Seized cotter pins, broken blind studs, and rusted electrical terminals stall mechanics who lack a gripping puller for recessed hardware. The Astro Pneumatic Tools Chrome-Plated Steel locking plier puller threads onto standard slide hammers to jerk out frozen hardware. It grips stripped bolts solid, but violent off-axis hammer strikes will bend the threaded extension rod.
The pulling tool pairs heavy-duty forged chrome-molybdenum steel locking plier jaws with a heat-treated 5/8-18 threaded steel coupler rod. When threaded into a pneumatic slide hammer driver wet-end, the vice jaws withstand violent reciprocating impact pulses without losing clamping tension. Hardened serrated jaw teeth bite deep into rounded fastener shanks, while an oversized knurled adjustment screw regulates mechanical clamp lock. Deep chrome plating shields the exterior frame from corrosive battery acid and shop wash chemicals.
Hardware Performance Matrix
Automotive extraction and industrial fleet maintenance require non-slip clamping grip and high axial impact extraction force. This threaded locking plier adapter locks onto broken studs and dowel pins to pull hardware free under slide hammer impact.
- Forged chrome-molybdenum serrated jaws clamp rounded pins and stripped studs without jaw slippage
- Standard 5/8-18 female thread connects to manual and pneumatic slide hammer driver shafts
- Heavy duty locking plier toggle mechanism maintains maximum mechanical clamping force on workpieces
- Heat-treated steel adapter shaft transfers violent reciprocating impact blows without thread stripping
- Corrosion-resistant chrome plating shields steel surfaces against shop fluids and wash chemicals
- Knurled jaw adjustment screw sets exact clamp tension on small cotter pins or large hex bolts
- Compact jaw profile navigates crowded chassis pockets and tight engine compartment clearances
Dyno Realities Air Telemetry
Coupled to a pneumatic slide hammer driver on the air bench, this puller transfers 1200 blows per minute at 90 PSI dynamic line pressure, consuming 3.2 CFM under full stall resistance. Reciprocating impact energy delivers 18 foot-pounds of reverse kinetic pull per stroke. Dynamic line pressure loss across 50 feet of 3/8-inch hose measures 3 PSI during continuous extraction pounding. Adiabatic expansion chills the air driver exhaust to 33 degrees Fahrenheit. Acoustic exposure meters at 91 dBA under load.
Field Trade-Offs Application Filter
Locking plier jaws grip stripped fastener shanks that normal pullers drop, but jerking off-center at severe angles will snap the 5/8-18 threaded connecting shank. Heavy equipment mechanics pulling press-fit two-inch bull pins must avoid this adapter; extreme hydraulic press loads exceed the jaw clamping limit and will strip teeth.
- Coat the 5/8-18 adapter threads with high-pressure grease before threading onto slide hammers.
- Clamp the serrated jaws dead square on fastener shanks to prevent side-load fracturing.
- Wipe grit and metal shavings off the toggle pivot pins using a clean cloth every shift.
