Buttress threads are designed to handle particularly high axial thrust while being able to release quickly. These threads typically feature a heavily slanted trailing face with perpendicular edges, giving them the unique ability to handle unidirectional loads. With as much shear strength as square threads, buttress thread designs are commonly used in large screw presses, vertical lifting applications, and other use cases.

Gage Assembly Co. offers buttress thread gauges along with other gauge designs that meet our customers’ specifications. Read on to learn more about buttress threads, their benefits, and how to find standard or custom products that perform in line with your specific needs.

Benefits of Buttress Thread Gauges

Buttress thread gage assemblies from Gage Assembly offer several unique advantages, including:

• Superior durability. O-6 tool steel heat treated and cold stabilized to 58-62 Rc. Hard chrome available for extra wear.
• High Limit Pitch Diameter. Standard practice at our factory includes manufacturing all thread gages on the high side of the P.D. tolerance for longer wear.

Typical Buttress Thread Gauge Applications

Buttress threads can handle some of the highest load capacities while handling unidirectional axial loads, making them popular in a wide range of applications across multiple industries. Applications for our buttress thread gauges include:

• Friction screw presses
• Artillery equipment
• Heavy lifting equipment in the oil field
• Transmission threads in milling and turning equipment
• High-load pressure machinery

Vertical lifting applications can use buttress thread gauges to support loads toward the screw thread’s upper flank. Additionally, these designs work to open and close bench vices in applications that only require unidirectional tensioning power. The thread’s single-direction parallel axis force forms a highly secure joint that allows for efficient re-tensioning, making these designs compatible with viscous liquid sealing applications.
