Slotted Countersunk Machine Screws DIN 963

Our Slotted Countersunk Machine Screws, or Slotted Countersunk Heads as they are also known, are manufactured to DIN 963 from high performance stainless steel, which provides an excellent level of resistance and strength across medium to heavy loads. These Countersunk Screws can sit flush into a pre countersunk recess, this can be useful to prevent snagging of wires and fabrics. These screws can also be used with Finishing Washers for non-countersunk flat surfaces.

Most commonly used in conjunction with Washers and Nuts, these products are used to hold fasteners in place, joining two or more parts together. We also offer Socket Screws and Hex Head Screws.

Our Slotted Countersunk Screws are available in A2 (Equivalent to 304) or A4 (Equivalent to 316 Marine Grade) Stainless Steel in metric sizes from M1 x 2 to M16 x 150. For our full selection of sizes and materials see the product table displayed below, or get in touch with a member of our staff.
