KZINO Wiper Arm Puller Tool 48mm (Jaw 6–28mm) — 45# Carbon-Steel Heavy-Duty Extractor

The KZINO Windshield Wiper Puller Tool is a heavy-duty, carbon-steel kit designed to remove wiper arms, conical-spline bolts, and stubborn battery terminal clips cleanly and without damage.

This compact puller uses hardened 45# carbon steel components and a knurled center screw so technicians and DIYers can extract wiper arms and battery terminal bearings precisely. Built for repeated professional use, the tool offers a jaw opening that accommodates a wide range of terminals and spline sizes while protecting posts and splined columns from bending or marring.

How does this tool safely remove stuck windshield wiper arms?

The KZINO puller places its screw pad on top of the spline column and uses even upward pressure to lift the wiper arm off the tapered spline, preventing twisting or leverage damage. Because the jaws grip beneath the cable clamp or arm flange, the force is concentrated where it can separate press-fit parts without prying.

• Hardened forged jaws resist bending under load for reliable grip.
• Knurled cone and center screw provide controlled, steady extraction.
• Fits conical spline installations and standard bolted wiper arms.
• Outer diameter 48 mm and collar ~15.2 mm for common wiper dimensions.

What sizes and materials are included, and will it fit my vehicle?

Manufactured from heat-treated 45# carbon steel, the puller is corrosion resistant and hard enough for workshop tasks. The jaw opening spans approximately 6–28 mm (1/16"–1-1/16") and the outer puller diameter is about 1-7/8" (48 mm), covering most passenger vehicle wiper terminals and many battery clip styles.

• Jaw opening: 6–28 mm (1/16"–1-1/16") for broad compatibility.
• Outer diameter: 48 mm to match typical spline heads and collars.
• Includes one wiper/battery terminal puller and one disassembly collar (≈15.2 mm).
• Durable 45# carbon steel with heat treatment for longevity.

Can this tool remove battery terminal clips without damaging the post?

Yes — the puller screw pad is designed to sit atop the terminal post so the clamp can be lifted straight off without crushing or bending the battery stud. The technique reduces twisting and helps preserve terminal integrity for reuse.

• Screw pad alignment prevents lateral stress on the battery post.
• Jaws engage beneath the clamp to lift cleanly rather than pry.
• Works on corroded or seized terminals where wrenches or pliers fail.
• Suitable for professional shops and roadside repairs.

How easy is it to operate for someone with basic tools experience?

Operation is straightforward: tighten the knurled cone, position the jaws under the clamp, then turn the center screw to raise the clamp or arm. No special power tools or adapters are required, and the design minimizes the need for excessive force or improvised leverage.

• Simple hand-turn center screw for controlled extraction.
• Knurled cone ensures secure seating on the spline or terminal.
• Direct mechanical action reduces risk of part breakage.
• Small, portable kit fits a toolbox or glove compartment.

Who is this for? The KZINO Windshield Wiper Puller Tool is aimed at mechanics, auto electricians, fleet maintenance staff, and home mechanics who need a compact, dependable tool to remove press-fit wiper arms, conical-spline bolts, and seized battery terminal clips. If you perform routine wiper replacement, battery work, or body repairs that require clean removal of splined components, this hardened carbon-steel puller provides repeatable results without harming posts or splines.
