Types of Set screws

Set screws come in different variants, with the five most popular styles being:

Cone point set screw

• Cone set screws exhibit superior torsional resistance due to concentrated axial loading.

• The conical tip induces localized deformation on planar substrates, enhancing mechanical interlock.

• Serves as a kinematic fulcrum for precision angular adjustments prior to final fixation.

• Optimized for stress concentration applications in low-yield-strength material assemblies.

flat point set screw

• Flat set screws apply uniform compressive stress distribution at the interface, minimizing surface penetration while offering reduced rotational resistance compared to profiled tips.

• Recommended for applications involving low-stiffness substrates or thin-walled assemblies where penetration must be controlled.

• Preferred for dynamically adjusted interfaces requiring repeated positional recalibration without surface degradation.

dog point set screw

• Flat-tip set screws engage pre-drilled holes, allowing shaft rotation while preventing axial displacement.

• Extended tips locate into machined shaft grooves for radial positioning.

• Functionally interchangeable with dowel pins in alignment applications.

Cup point set screw

• Concave tip profile generates radial micro-indentations, creating anti-rotation interference fit.

• Optimized for dynamic loading applications through enhanced frictional retention.

• Produces characteristic circumferential witness marks upon installation.

• Hemispherical end geometry with negative curvature profile.

Nylon point set screw set screw

• Elastomeric tip conforms to irregular surface topographies

• Viscoelastic deformation enables full surface contour adaptation

• Provides mar-free high-retention fastening solutions

• Effective on non-prismatic shafts including eccentric or oblique geometries

FAQ

1. Q: Why do set screws loosen easily?
A: Causes: vibration, material creep, or insufficient installation torque.
Solution: Use thread glue or matching lock washers.

2. Q: How to choose the end type?
A: Cone end: high hardness shaft (steel/titanium alloy).
Flat end: soft materials such as aluminum/plastic.
Cup end: general balancing scenario.

3. Q: Is it necessary to control the torque during installation?
A: Yes. Over-tightening may cause stripping or component deformation. It is recommended to use a torque wrench and refer to the manufacturer's manual.

4. Q: Can it be reused?
A: If the thread is not damaged and the end is not worn, it can be reused, but the locking performance needs to be checked.

5. Q: What is the difference between set screws and ordinary screws?
A: Set screws have no head and rely on end pressure to fix; ordinary screws connect components through the clamping force of the head and thread.
