Automated insertion for threaded pins, set screws and studs
Discuss specialist fastening requirements with AFTSL. We can review your threaded element, installation target and potential tooling route, including whether LEETX tightening components are suitable for the application.

Tooling matched to the threaded element
Set screws, threaded pins and studs require an application-specific approach to feeding and driving. Headless or unusual fasteners may need dedicated gripping, insertion and depth-control equipment. Suitability of LEETX components must be confirmed for the exact fastener; standard screw-feeding equipment should not be assumed to cover these applications.
AFTSL can discuss these specialist tooling requirements using the fastener drawing and the component detail. The description “stud” or “set screw” alone is not enough to establish compatibility: the shape, drive feature and required installed position matter.
Fastener detail
Provide the length, thread, end form and drive feature. Identify whether several different threaded elements share the station.
Installed condition
Show the required final position, including any specified depth or projection, and your acceptance criteria.
Assembly equipment
Describe the intended machine layout, the direction of insertion and how the component is located during the cycle.
What to send for an application review
Include the fastener and workpiece drawings together. Mark the installed position and any nearby features that limit the tool envelope. Where a previous system has struggled, explain the issue and the conditions under which it occurs.
- Threaded-element specification and representative samples.
- Component material and mating-thread details.
- Required installed position and tightening instructions.
- Target output and the number of insertions per assembly.
- Existing tooling, controls and available mounting space.
- Variant changes and project timing.
For an assembly that uses several fastening types, identify each type separately so its tooling requirement can be discussed clearly.
Frequently asked questions
Automatic Set Screw and Stud Insertion: answers to common application and specification questions.
Can the same unit handle every threaded element?
Compatibility must be checked against the individual fastener. Nosepiece, feeding and driving requirements can change with its dimensions and drive feature.
What if my fastener has no conventional head?
Send a detailed drawing or sample and describe the required installation. The gripping, drive and feeding methods need application review, with manufacturer confirmation before any LEETX component is specified.
How is the final stud or set screw position specified?
Define the required installed position on the component drawing, including depth or protrusion and any tightening requirement. Include the tolerance and inspection method so the intended result is clear before tooling is selected.
Why do fastener length and drive features matter?
They influence how the threaded element is sorted, presented, held and driven. Headless fasteners may need a different handling arrangement from conventional screws, so provide the complete fastener drawing rather than the thread size alone.
Can coated or pre-treated threaded elements be assessed?
Include the coating or pre-applied treatment in your enquiry and provide samples where available. Handling and insertion requirements should be reviewed for the actual production fastener, including any restrictions on surface damage or contamination.
