Metric Steel Pan Head Slotted Screws, Install these metric pan head screws for a low-profile, finished look—no countersink required. With a chamfered or slightly domed head, they won't catch on clothing or straps as you pass by. A layer of zinc plating protects the steel from rust in wet areas but won't hold up to salt water and chemicals. Length is measured from under the head.
All of these screws meet DIN or ISO dimensional and material standards, so you know they'll fit with other parts and tools. Although DIN 85 is no longer active and has been superseded by ISO 1580, it's still a relevant standard that's referenced by engineers and designers. The two standards are functionally equivalent.
Wide-head screws evenly distribute clamping force and eliminate the need for a washer. While they may not fit into tight spots, they're a good option for fastening thin material, or when the screw hole is much larger than the diameter of the screw.
