Made from 18-8 stainless steel, these metric button head screws have good chemical resistance and may be mildly magnetic. The tamper-resistant Torx drive (also known as a pin-in Torx drive) makes them difficult to remove without special tools.

To prevent unwanted removal, these screws have a tamper-resistant Torx drive—also known as a pin-in Torx drive—that makes them difficult to unscrew without special tools. An O-ring under the head blocks leaks and seals out dust and dirt.

Nearly twice as strong as stainless steel button head screws, these metric screws are made from alloy steel. Their tamper-resistant Torx drive (also known as a pin-in Torx drive) makes them difficult to remove without special tools.

Made from 18-8 stainless steel, these metric button head screws have good chemical resistance and may be mildly magnetic. The tamper-resistant hex drive (also known as a pin-in hex drive) makes them difficult to remove without special tools.

The extra-wide head distributes holding pressure to reduce the likelihood of crushing thin materials.

A tamper-resistant drilled spanner drive makes these screws difficult to remove without special tools. They're 18-8 stainless steel for good chemical resistance and may be mildly magnetic.

Stainless steel screws have excellent corrosion resistance in most environments.

These button head screws have a unique drive that is sold only by McMaster-Carr, making them difficult to remove without a special driver bit. Made from 18-8 stainless steel, they have good chemical resistance and may be mildly magnetic.

With a tamper-resistant Torx drive (also known as a pin-in Torx drive), these metric screws are difficult to remove without special tools.

Prevent unwanted removal, leaks, and contamination with these sealing Torx screws.

These metric screws have a tamper-resistant drilled spanner drive, making them difficult to remove without special tools.

A tamper-resistant hex drive (also known as pin-in hex drive) makes these screws difficult to remove without special tools.
