Alloy Steel Socket Head Screw with Split Lock Washer
Manufacturer part: 90342A129
Screws are alloy steel with a tensile strength of 180,000 psi, making them stronger than Grade 8 steel screws and more than two and a half times stronger than stainless steel screws with a split lock washer. Their black-oxide finish provides mild corrosion resistance in dry environments. Also known as Sems screws, they have a permanently attached but freely rotating split lock washer that adds tension to resist loosening from vibration. Length is measured from under the head.Coarse threads are the industry standard; choose these screws if you don’t know the threads per inch.
