Product Overview
This series of Dual-Injection Handle Slotted Screwdrivers is designed for heavy-duty applications across electrical enclosure mounting, automotive repair, and industrial maintenance. The shank is forged from premium 6150 Chromium-Vanadium (Cr-V) alloy steel and whole-quenched to ensure optimal hardness and high torque performance. The PP+TPR dual-injection molded grip features anti-slip contours that resist motor oil and grease, delivering maximum comfort and power transfer. Notably, the lineup includes Cabinet Tip design options (marked with ⋆, where a=c), enabling smooth entry into deep recessed screw holes without shoulder interference.
Product Features
- Premium 6150 Cr-V Steel Shank: Expertly quenched and heat-treated for maximum toughness and high torque capacity, preventing tip deformation and rounding.
- Cabinet/Parallel Tip Design (⋆ Marked Items): Features equal tip width and shank diameter (a=c). Perfect for reaching deep, narrow screw channels in electrical control boxes.
- Ergonomic Dual-Injection Soft Grip: Molded with PP+TPR materials for an anti-slip friction hold that reduces hand strain during repetitive driving.
- Strong Magnetic Blackened Tip: Precision-ground black oxide tip resists corrosion and strongly attracts steel fasteners for hassle-free single-handed alignment.
- Full Specification Coverage: Offers 38mm stubby models (a style for tight spots), cabinet deep-reach models, and extra-long 300mm shafts.

FAQ
Q1: What is special about the items marked with an asterisk (⋆)?
A: Items marked with ⋆ feature a “Cabinet Tip” (or parallel tip) design where the tip width (a) equals the shank diameter (c), such as a=3mm,c=3mm. Unlike standard flared slotted tips, cabinet tips fit straight into deep, narrow holes or electrical box channels without snagging.
Q2: What do the dimensions a,b, and c represent in the spec table?
A: a represents the Tip Width; b represents the Tip Thickness at the driving edge; c stands for the Shank Diameter of the metal rod.
Q3: Why choose 6150 Cr-V steel over basic carbon steel?
A: 6150 Cr-V steel undergoes complete heat treatment to achieve HRC 52–56 hardness, offering up to 3x higher torque capacity and wear resistance compared to basic 45# carbon steel.
Q4: Is the dual-injection handle resistant to automotive oil and solvents?
A: Yes! The PP+TPR dual-shot handle is formulated to resist degradation, swelling, or stickiness when exposed to motor oil, grease, or solvents.
Q5: Can you manufacture private label screwdrivers with our custom logo?
A: Yes! We offer full OEM/ODM services, including laser marking on the shank, handle logo printing, custom handle colors, and custom retail packaging (blister cards, display boxes, etc.).
