Stainless Steel Slotted Thumb Screws

 

Stainless steel slotted thumb screws are made of high-quality stainless steel 304/316, which has both corrosion resistance and convenient manual operation. Its slotted design is compatible with ordinary screwdrivers or coins, while the knurled head supports direct finger tightening, which is suitable for scenes that require frequent adjustment or when tools are inconvenient to use.

1. Highly corrosion-resistant stainless steel material
304 stainless steel:
Passed the salt spray test for ≥72 hours, far exceeding ordinary galvanized screws. Suitable for humid environments (such as kitchens and bathrooms).
316 stainless steel:
Suitable for harsh environments such as seawater and chemical equipment, and its salt spray test can reach more than 500 hours through passivation.

2. Stainless steel slotted thumb screws, slotted drive + thumb screw design, taking into account versatility and convenience
Slotted drive:
Simple structure, can be operated by a slotted screwdriver, coin, or blade for emergency operation, and has strong compatibility.
Limitations: The slot contact surface is small, and the torque resistance is weaker than the cross slot or hexagon socket. It is recommended for light load scenes with torque ≤0.5N·m.
Knurled head:
The knurled texture or wing-shaped edge increases friction, allowing for bare-hand tightening without the need for tools, making it suitable for narrow spaces or quick assembly.

3. Precision machining to ensure reliability
Notch accuracy: CNC turning is used to form the groove, with uniform groove depth to reduce the risk of screwdriver slippage.
