Tamper-Resistant Hex Drive Flat Head Screws
Standard Profile
Undercut Profile
A tamper-resistant hex drive (also known as a pin-in hex drive) makes these screws difficult to remove without special tools. For installation tools, see tamper-resistant hex drivers and bits. Made from 18-8 stainless steel, they have good chemical resistance and may be mildly magnetic. All are passivated for added protection against oxidation and corrosion. They’re angled under the head to sit flush within countersunk holes. Length is measured from the top of the head.
Screws with an undercut profile have a shallow head for use in thin materials.

Metric Stainless Steel Tamper-Resistant Button Head Hex Drive Screws
Made from 18-8 stainless steel, these button head screws have good chemical resistance and may be mildly magnetic. They’re passivated for added protection against oxidation and corrosion. The tamper-resistant hex drive (also known as a pin-in hex drive) makes them difficult to remove without special tools. For installation tools, see tamper-resistant hex drivers and bits. Length is measured from under the head.

Alloy Steel Tamper-Resistant Button Head Hex Drive Screws
Made from alloy steel, these screws are nearly twice as strong as stainless steel button head screws. They have a black-oxide finish that provides mild corrosion resistance in dry environments. Their tamper-resistant hex drive (also known as a pin-in hex drive) makes them difficult to remove without special tools. For installation tools, see tamper-resistant hex drivers and bits. Length is measured from under the head.
