Independent Loading Mechanism (ILM)
4.1.3
Shoulder Screw and Fasteners Design Overview
The shoulder screw is fabricated from carbonized steel rod. The shoulder height and
diameter are integral to the mechanical performance of the ILM. The diameter provides
alignment of the load plate. The height of the shoulder ensures the proper loading of
the IHS to seat the processor on the socket contacts. The design assumes the shoulder
screw has a minimum yield strength of 235 MPa.
Note:
The reference design incorporates a T-20 Torx* head fastener. The Torx* head fastener
was chosen to ensure end users do not inadvertently remove the ILM assembly and for
consistency with the LGA1366 socket ILM.
