Tooling source notes
- MBF2003 §7.5: "In those instances where special driving tools are adopted by the user, wrenching speed of this tooling shall not exceed 600 RPM." §4.3: "It is required that only the approved tools listed in Paragraph 3 of this specification be used for the installation of these fasteners."Specification, not interview: Monogram MBF2003 Rev AG.
- Alternative tooling works in practice: roughly 500 RPM with the right torque and fittings, and shops fabricate the fittings in house. Check it against the manufacturer's speed limit for user-adopted tools before relying on it.Installer interview (aerospace tool services), 2026-09-25. Field experience, not a specification.
- Monogram factory tooling was quoted at 23 to 24 weeks lead time. Order tooling with, or before, the first fasteners.Installer interview (aerospace tool services), 2026-09-25. Field experience, not a specification.
- Repair access is the edge case that bites: you can't strip the surrounding structure during a repair, and some jobs need 90° drills and heads. Know the tool envelope during design.Installer interview (aerospace tool services), 2026-09-25. Field experience, not a specification.
Removal (drill-out)Published procedure
Monogram MBF2003 Rev AG (Composi-Lok II), §8 Removal and Figure 9
- “Composi-Lok II may be removed with the tooling shown in Figure 9 of this specification. Complete kits are available from Monogram Aerospace Fasteners. Contact factory for details.” Monogram MBF2003 Rev AG (Composi-Lok II install spec), p.18, §8.1 ↗
- “Corebolt protrusion should be milled flush prior to removal.” Monogram MBF2003 Rev AG (Composi-Lok II install spec), p.12, Figure 9, Table 9 ↗
- “A complete tool consists of the air motor module (RM3197), a nose piece module (column 3) and a carbide star drill (column 4). A depth gage (column 6) is required for setting drilling depth.” Monogram MBF2003 Rev AG (Composi-Lok II install spec), p.12, Figure 9, Table 9 ↗
- “Use flush head style nose piece modules for non-hexagonal protruding head fasteners (e.g. MBF2110 and MBF2120).” Monogram MBF2003 Rev AG (Composi-Lok II install spec), p.12, Figure 9, Table 9 ↗
Cautions
- “If a fastener has been removed, the same diameter Composi-Lok II can be reinstalled provided the hole has not been damaged. In the event that the hole has been damaged, the next larger diameter Composi-Lok II should be used (NOTE: for flush head fasteners the countersink will have to be deepened).” Monogram MBF2003 Rev AG (Composi-Lok II install spec), p.14, §4.6 ↗

Cautions
- “This kit is used to remove alloy steel, titanium and A-286 Visu-Loks or A-286 and titanium Composi-Lok fasteners. To remove H-11 and similar material, contact factory for details.” Monogram MBF2301 Rev NR (Composi-Lok 3 install spec), p.12, Figure 9, note 2 ↗
None of the removal procedures on file gives a composite-specific removal caution. The Monogram specs address composite at the hole instead: holes "reasonably round and free from burrs (metallic structure) and delamination (graphite/epoxy type structure)" (MBF2003 §5.1).
Tool tables are the manufacturer's as published in the cited revision; confirm current tool PNs with the manufacturer or distributor before purchase. Not a certified process authority: install and remove per the OEM process specification.

Put the tooling on the RFQ
The RFQ package adds these tools and gauges for the diameters on your lines, so the supplier quotes them with the fasteners.
