Socket head cap screws are used for applications with limited space. They have cylindrical head and internal wrenching features (mostly hexagon socket) that allow them to be used in locations where externally wrenched fasteners aren’t desirable.

They are used for critical vehicle applications, machine tools, tools and dies, earth moving and mining machinery, and a wide range of engineering applications. The most important reasons for the increasing use of socket head cap screws in industry are safety, reliability and economy

1936-SERIES AND 1960-SERIES
This term is generally used in America. The original configuration of socket head cap screws didn’t maintain consistent relationships among the nominal shank diameter, head diameter, and socket size throughout the available size range. This limited the performance potential of some sizes.

In the 1950s, one socket screw manufacturer in America performed extensive studies to optimize performance based on geometry, fastener material strength, and applications. These studies resulted consistent dimensional relationships throughout the size range.

Eventually, these relationships were accepted as industry standards and the year of acceptance – 1960 – was adopted to identify the optimized designs. The term 1936-Series was selected to identify the older style for replacement requirement.

Socket and Allied carry a vast range of both 1936 and 1960 Socket Cap Screws where odd and particular sizes are required for a specific application.

Socket and Allied can manufacture Socket Cap Screws in a whole range of alloy metals including exotic stainless steels and yellow metals.

ADVANTAGES OF SOCKET HEAD CAP SCREWS
- As compared to ordinary fasteners, less socket screws of the same size can achieve the same clamping force in a joint.

- As fewer screws are required for a given job, fewer holes are required to be drilled and tapped.

- There is weight reduction as fewer screws are used.

- There will be weight reduction on account of smaller size of the component parts since the cylindrical heads of socket screws need less space than hex heads and require no additional wrench space.
