Socket Head Cap Screw (Special Low Head)

SSH

The height of the screw head is 1.5 mm or less, regardless of the screw size. The head of the screw goes unnoticed after installation.
Compact size with safety improvements for equipment and devices
Strength Classification:
[SSH][SSH-EL] ―――――― Thread: 10.9 Head: 5.8
Please Note: Strength levels have been raised with heat treatments; however, the head strength is weaker than normal hexagon socket head cap screws.
SSHS ―――――――――― A2-50
Material/Finish
SSH ――――――― SCM435 Equivalent, Ferrosoferric Oxide Coating (Black)
SSH-EL ――――― SCM435 Equivalent, Electroless Nickel Plating
SSHS ――――― SUSXM7 (SUS304 Equivalent)
SVSHS Socket Head Cap Screw (with Ventilation Hole/Special Low Head) is also available.
