Screw Jack Head Types – Cylindrical, Flanged, Threaded & Flat Head Explained
Screw Jack Head Types – Choose the Right Connection
The screw head (or screw end) is the connection point between the screw jack and your load. Different head types suit different attachment methods.
The Four Standard Head Types
| Head Type | Code | Description | Best For |
| Cylindrical | R / I | Plain cylindrical end | Slip-fit connections, custom attachments |
| Flanged | T / II | Flanged end with bolt holes | Bolted connections, rigid mounting |
| Threaded | S / III | Threaded end | Nut attachment, adjustable connections |
| Flat head | H / IV | Flat end | Push applications, custom tooling |
How to Choose
Cylindrical (R) : Choose when you need a simple pin or clamp connection
Flanged (T) : Choose when you need a rigid, bolted connection
Threaded (S) : Choose when you need adjustable height or nut attachment
Flat head (H) : Choose for pushing applications or custom tooling
