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.

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.

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.

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

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.

Install and remove these screws with a tamper-resistant spanner driver.

The S-shaped drive can be installed with a standard slotted driver, but requires a special tool for removal.

A tamper-resistant Torx driver is required for installation and removal. Also known as pin-in-Torx, these screws allow you to apply extra force with less slippage or damage to the recess.

Also known as pin-in-hex, install and remove these screws with a tamper-resistant hex driver.

A tamper-resistant Torx driver is required for installation and removal. Also known as pin-in-Torx, these screws allow you to apply extra force with less slippage or damage to the recess.

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

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

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

Stainless steel screws have excellent corrosion resistance in most environments. Wire these screws together for more vibration resistance than other types of socket head screws.
