Slotted Head Hand-Tightened Screw - Z-Shaped ABS Plastic Head, Anti-Slip Knob Bolt
Core Features

Tool-Free Operation: The ergonomic Z-shaped ABS head allows easy hand-tightening/loosening—no screwdrivers, wrenches, or other tools required. Perfect for quick assembly, maintenance, or adjustments.
Durable Material Combo:
Head: High-quality ABS plastic (resistant to impact, wear, and corrosion; available in multiple colors).
Body: 35# carbon steel with galvanized surface treatment (prevents rust, enhances tensile strength, meets 4.8-grade strength standards).
Anti-Slip Design: The Z-shaped head’s textured surface boosts friction, ensuring a secure grip and preventing slippage during use—critical for oily or wet workspaces.
Multiple Customization Options: Choose from black, white, yellow, red, gray, blue, or custom colors for the plastic head. We also offer nickel plating or stainless steel body upgrades upon request.
Ample Stock & Fast Delivery: Common specifications are in stock (up to 1,000,000 pieces for select sizes), with delivery within 48 hours for standard orders.
