Tamper-Resistant Hex-Drive Stainless Steel Button Head Screws
 |
Our most corrosion-resistant hex-drive screws for preventing unauthorized access. Also known as pin-in-hex and pin-in-socket drives, these screws have a security pin in the drive that you can only turn with a tamper-resistant hex driver. The deep six-point opening helps them withstand torque without damaging the drive. The button head looks similar to a pan head, but it's lower and more compact, taking up less space.
Length is measured from under the head.
18-8 Stainless Steel—The choice for wet and outdoor environments, these screws won't rust. However, they don't hold up to the harsh chemicals that 316 stainless steel can.
Power Tool Bits—Pair these bits with your power tools to turn screws more quickly than manual tools.
