Steel Socket Head Screws with Flat Washer

Protect thin and soft surfaces from damage. A freely rotating washer sits between the head of these screws and your material to distribute pressure evenly. Made of alloy steel, these are some of our strongest screws. Their deep, six-point socket keeps hex keys from slipping out and damaging the drive. Length is measured from under the head.

• Black-Oxide Alloy Steel— Best for dry environments since moisture will cause these screws to rust. They have a dark, matte appearance.
