Heavy-Duty Go-Through Screwdriver with Insulated Grip

Industrial go-through striking screwdriver forged from 6150 Cr-V steel with full heat treatment. Features a steel end-cap for hammer strikes and an insulated molded handle for safety and ergonomic comfort. Built for loosening stubborn or rusted screws in auto repair and machinery maintenance.

Product Overview

Engineered for demanding applications, this Go-Through Striking Screwdriver with Insulated Handle seamlessly combines hammering capability with safety and ergonomic comfort. The shank is forged from premium 6150 Chromium-Vanadium (Cr-V) alloy steel and whole-quenched to deliver high toughness and anti-snap torque performance. Its solid steel shaft extends completely through the handle to a heavy-duty striking cap, allowing you to use a hammer to break rust bonds on seized screws. Molded with an insulated, contoured handle, it offers a secure, comfortable, and safe grip for mechanics and technicians.

Product Features

  1. Premium 6150 Cr-V Steel Shaft: Heat-treated and fully quenched for high hardness and wear resistance, maintaining tip integrity under severe impacts.
  2. Go-Through Striking Steel Cap: The full-length steel core terminates in a heavy-duty end-cap, designed to withstand hammer strikes to shock loose rusted or frozen fasteners.
  3. Insulated Ergonomic Handle: Molded with high-durability insulating composite material, providing superior grip comfort, non-slip friction, and extra electrical safety.
  4. Precision Magnetic Tip: Precision-machined cross/slotted tip profile minimizes slipping (cam-out), while the strong magnetic charge holds screws securely.
  5. Hexagonal Drive End-Cap: The striking end cap features a hex shape allowing extra wrench leverage when breaking loose maximum-torque screws.

FAQ

Q1: How does a “Go-Through” screwdriver work?
A: A go-through screwdriver features a continuous steel shank running from the tip through to a steel end-cap on the handle. When struck with a hammer, the impact passes directly through the steel shaft to shock loose rusted screws without damaging the handle.

Q2: Is the insulated handle safe for electrical work?
A: The handle is molded from insulating material to reduce accidental shock risks and enhance user safety. However, for live high-voltage work (e.g., up to 1000V live environment), dedicated VDE-certified insulated tools should be used.

Q3: Will the handle shatter or break after repeated hammering?
A: No. Because the impact energy travels directly down the internal steel core, the handle body experiences minimal stress, preventing cracking or detachment.

Q4: Is the tip magnetic?
A: Yes, the tip is magnetized to hold screws firmly, allowing convenient single-handed operation in awkward angles.

Q5: Can you manufacture private label screwdrivers with our custom logo?
A: Absolutely! We offer full OEM/ODM options, including laser marking on the shank, handle logo printing, custom handle colors, and custom retail packaging (blister cards, display boxes, etc.).
