SOKO SH88ZCM120025 M12 x 25mm Socket Head Cap Screw, Class 8.8, Zinc Plated

The SOKO socket head cap screw on this page is a metric screw in class 8.8 with a zinc plated finish. This page lists 8 items from M12 and M16, in lengths from 25mm to 50mm.

The fastener acronym list names this head style: SHCS, Socket Head Cap Screw (manufacturer-stated).

The head carries a socket, so the screw is driven with a key or bit instead of a spanner.

The item description names DIN 912 (manufacturer-stated).

The class table lists class 8.8 as medium carbon steel, quenched and tempered (manufacturer-stated). The tensile and proof figures in the table are the class minimums for the size range the table states, not a test result for the screw.

The pitch shown for each size is the coarse pitch given in the thread table (manufacturer-stated).

Pack quantity is shown for each item. It changes with the size and length.

The item descriptions do not give the socket (key) size, head dimensions or thread length for these screws, so none are published.

Selecting the right option

Choose the thread first: the screw must match its nut or tapped hole in diameter and pitch. Metric sizes are the nominal diameter in millimetres; compare the pitch in the tables with your thread. By convention the length of a socket head cap screw is measured from under the head; the item description does not state the measuring point. Check the key size against the screw in hand, as the item description does not state it. For a different class or finish see the related pages.
