Stainless Steel Hex-Head Thumb Screws
 |
When you need more torque than fingers alone can provide, crank these stainless steel thumb screws with a wrench. For finger tightening, the thick, hex-shaped head transmits added torque for a stronger hold than other head shapes. These thumb screws aren't recommended for structural, load-bearing applications.
Length is measured from under the head.
18-8 Stainless Steel—The choice for wet and outdoor environments, these screws resist rust. However, they won't hold up to the harsh chemicals that 316 stainless steel can.
