Gashwer Wiper Arm & Battery Terminal Puller 6–28mm — Dual-Function Forged Steel

Gashwer's combined wiper arm and battery terminal puller is a heavy-duty hand tool engineered to remove windshield wiper arms and battery terminal clamps safely without damaging splines, posts, or surrounding bodywork.

This compact, forged steel puller pairs a claw-style wiper-arm remover with a center-screw bearing puller so technicians and DIYers can extract fixed or ball-bearing wiper arms and loosen battery terminal clamps on tapered or splined shafts. Built from heat-treated 45# carbon steel and designed to seat solidly on arm bases, the tool provides controlled, axial force to separate tight-fit components while protecting the vehicle's finish.

How does this tool remove stuck windshield wiper arms?

The Gashwer puller grips the wiper arm base and applies steady center pressure through a hardened screw to lift the arm off its tapered or splined shaft. Its jaws are shaped to seat under the arm flange so force is concentrated where needed, reducing leverage on the hood or trim.

• Claw-style foot clamps securely to arm base for stable pulling
• Hardened center screw forces the arm straight off the spline
• Works on both fixed and bar-and-ball bearing wiper assemblies
• Jaw opening range: 6–28 mm to fit most passenger vehicles

Can I use this for battery terminal clamp removal without harming the post?

Yes — the puller includes a screw pad designed to contact the top of the battery post spline so the clamp can be lifted off evenly. Applying axial pressure avoids prying or twisting that can mar or deform the battery post.

• Screw pad matches spline top to distribute force evenly
• Controlled turning prevents bending or crushing of terminals
• Dual-purpose design eliminates the need for separate tools
• Compact size fits into tighter engine-bay spaces

What materials and sizes make this tool durable and versatile?

The puller is forged from 45# carbon steel and undergoes a special heat-treatment process to increase hardness and corrosion resistance. The combination of robust jaws and a strong center screw gives the tool long service life under professional use.

• Material: heat-treated 45# carbon steel for strength and wear resistance
• Jaw opening: 1/16" to 1-1/16" (6–28 mm) for broad compatibility
• Outer diameter: 1-7/8" (48 mm) keeps the tool compact
• Includes an additional wiper arm remover collar (~15.2 mm) for fitment

Is this easy to use for non-professionals?

The Gashwer puller is designed with clear contact points and a simple center-screw action, making it straightforward for weekend mechanics while still meeting professional demands. Proper seating of the jaws and steady screw rotation will remove arms or terminals without excessive force or complex setup.

• Set the tool foot under the arm base and clamp securely before turning
• Tighten the center screw slowly to feel when the arm begins to lift
• No special adapters required for most common vehicles
• Compact form makes storage and transport easy

Who is this for: The Gashwer Wiper Arm and Battery Terminal Puller suits automotive technicians, body-shop technicians, fleet maintenance crews and DIY car owners who need a reliable, durable solution to remove stubborn wiper arms and terminal clamps without damaging posts, splines or vehicle bodywork. It’s particularly valuable when working on older or weathered vehicles where corrosion and tight fits make removal difficult, and for anyone who prefers a single multipurpose tool to reduce clutter in their toolkit.
