Temporary Fasteners for Aircraft Sheet Metal Work

Cleco fasteners are widely used during aircraft sheet-metal fabrication and repair to temporarily hold overlapping panels, skins, doublers, ribs, brackets, and other components in alignment before permanent riveting or fastening. They allow technicians to position parts, check fit, drill or ream additional holes, and maintain alignment throughout an assembly sequence.

The Spenro collection at Pilots HQ includes temporary fasteners in multiple diameters for different drilled-hole requirements. Available sizes include 3/32 inch, 1/8 inch, 5/32 inch, and 3/16 inch. Selecting the correct diameter helps support proper panel alignment without unnecessarily enlarging or damaging the prepared fastener hole.

Pushbutton and Temporary Cleco Fastener Pins

The HC1-8 pushbutton fastener features a cylindrical body, spring-loaded plunger, locking elements, and spreader mechanism. It is designed to temporarily secure steel or aluminum panels during precision drilling and riveting operations.

The collection also includes TP75 and AT-series Cleco fastener pins in several sizes. These products give aircraft mechanics, sheet-metal technicians, builders, and restoration shops options for organizing temporary fastening tools by hole diameter and job requirement.

Choose the Correct Cleco Diameter

Use the fastener size specified by the applicable drawing, repair data, or work instructions.
Match the Cleco diameter to the prepared hole rather than forcing an oversized fastener into place.
Inspect temporary fasteners for bent components, weak springs, contamination, or damaged locking elements.
Keep different diameters separated or clearly identified to reduce selection errors.
Confirm that temporary fasteners are removed before installing permanent rivets or closing an assembly.

Spenro TP6781 Rivet-Hole Brush

The Pilotshq assortment also includes the Spenro TP6781 rivet-hole brush. Rivet-hole brushes may be used during sheet-metal preparation to help remove loose chips, light debris, and residue from prepared holes before inspection or fastening.

Hole preparation is an important part of producing a sound riveted joint. Burrs, metal chips, sealant residue, corrosion products, or other contamination can affect component seating and joint quality. Use the brush only as appropriate for the material, hole size, and approved maintenance or fabrication process.

Aircraft Fabrication and Repair Applications

Spenro Cleco fasteners can support a variety of aviation sheet-metal tasks, including skin replacement, structural repairs, patch fabrication, panel fitting, experimental-aircraft construction, restoration projects, and training exercises. They may also be useful for non-aircraft fabrication where temporary alignment of drilled sheet material is required.

Temporary fasteners are positioning tools and do not replace permanent aircraft hardware. They should not be treated as load-carrying flight hardware or left installed in a completed aircraft assembly.

Use Approved Aircraft Maintenance Data

Aircraft structural work should be completed by appropriately qualified personnel using current approved technical data. Before drilling, reaming, deburring, cleaning, or riveting, consult the applicable structural repair manual, maintenance manual, engineering drawing, manufacturer instructions, or other authorized procedure.

Verify the required hole diameter, rivet type, edge distance, spacing, material thickness, grip range, surface treatment, and corrosion-protection process before beginning work. Cleco fastener color or appearance alone should not be used as the sole method of confirming size.
