Introduction

Square Head Set Screws, or often simply called "set screws," are fasteners used to secure a component relative to another by applying clamping force through the screw tip. The square head provides a large surface area for tightening with a wrench, allowing high torque for secure positioning. Unlike common socket set screws, the external head makes them ideal for manual adjustment in heavy machinery and older equipment standards where robustness is prioritized over flush design.

Key Feature

High Torque Capability

Applications

  • Heavy Machinery and Equipment: Used for adjusting and locking mechanical parts.

  • Pulleys and Gears: Securing these components onto shafts to prevent rotation.

  • Industrial Jig and Fixtures: Providing adjustable, high-force holding points in manufacturing tools.

  • Pipe Clamps and Collars: Used to fix position along a pipe or rod.

Advantages

  • Manual Adjustment: The external head allows for easy, quick adjustment and locking using standard wrenches.

  • Maximum Tightening Torque: The large square head transfers significantly more torque than internal drive set screws.

  • Durable Tip Selection: A variety of tip points are available to suit different application needs (e.g., cup point for semi-permanent setting, flat point for positioning).

  • Robust Design: Preferred in dirty or high-wear environments where internal drives might clog.

Payment & Shipping

We accept payments via TT and offer competitive bulk pricing. Set screws are shipped in sturdy, moisture-proof containers to protect the threads and tip points from damage, especially for alloy steel versions with black oxide finish.

FAQ

  • Q: What is the main difference between a square head set screw and a socket set screw?
  • A: The square head set screw has an external head, designed for high torque and easy external adjustment. A socket set screw (internal hex drive) is typically used when the screw needs to be flush or below the surface of the component, often requiring a lower tightening torque limit.
  • Q: How do I select the correct point style for my application?
  • A: Choose a Cup Point for permanent or semi-permanent setting on harder shafts; a Cone Point for precise positioning (creating a small indentation); and a Flat Point when you need to clamp against a hardened surface without damaging it.
