Installation tooling guide
The drawing calls out the fastener; the floor has to install it. This is what each family demands: the tool class, whether it is captive to the manufacturer, how much training a conforming install takes, and what inspection looks like afterward. Compiled from the same cited datasheets as the catalog.
Standard shop tooling
Installs with tools most sheet-metal shops already own: pull guns, rivet guns, wrenches. Lowest barrier, no capital purchase, easy second-sourcing of labor.
- Tool
- Hand or pneumatic pull gun
- Training
- Minimal, basic shop skill.
- How the install works
- Ubiquitous shop pull gun pulls the mandrel to upset the blind head.
- Post-install inspection
- Visual: mandrel break flush, head seated.
- Tool
- Hand / pneumatic / pneumatic-hydraulic pulling head
- Training
- Standard; Cherry offers global training.
- How the install works
- Self-contained installation washer eliminates worn-anvil problems; wide range of offset and right-angle pulling heads for access.
- Post-install inspection
- Visibly inspectable mechanical lock; protrusion check.
- Tool
- Standard CherryMAX tooling
- Training
- Standard.
- How the install works
- Runs on standard CherryMAX pulling heads, no tooling change needed.
- Post-install inspection
- Protrusion + lock check; confirm gap pulled out.
- Tool
- Standard pulling head
- Training
- Standard.
- How the install works
- Large bulged blind-side footprint forms over a much wider area than a standard rivet, distributing bearing across the laminate.
- Post-install inspection
- Locked spindle visible; bulb formation.
- Tool
- Hex key (holds pin) + collar wrench
- Training
- Standard; widely trained.
- How the install works
- Pin held stationary by a hex key while the collar is driven; a frangible wrenching tip shears off at a preset torque: automatic torque-off, no post-install torque inspection.
- Post-install inspection
- Collar break-off confirms torque; protrusion gauge.
- Tool
- Hex key + collar wrench
- Training
- Standard.
- How the install works
- Shorter thread form than Hi-Lok for ~15% weight saving at equal shear; recess designed for clearance-fit composite assemblies. Collars not back-compatible with Hi-Lok.
- Post-install inspection
- Collar break-off; protrusion gauge.
- Tool
- Rivet gun + bucking bar (both sides)
- Training
- Standard sheet-metal skill.
- How the install works
- Driven with a gun on the head side and a bucking bar on the far side: the upset requires back-side access and impact, which crushes/delaminates composite.
- Post-install inspection
- Shop-head diameter/height gauge.
- Tool
- Conventional pull tool
- Training
- Standard rivet-gun skill.
- How the install works
- 360° internal lock with a self-plugging blind-side upset; a visible circle-lock groove confirms a good install. Fills irregular holes other rivets can't.
- Post-install inspection
- Circle-lock groove visible; mandrel flush break.
- Tool
- Rivet gun + bucking bar (both sides)
- Training
- Standard riveting; composite bucking needs care.
- How the install works
- Standard bucking; the Hollow-End variant uses a soft upset so it can be set in composite without splitting the laminate.
- Post-install inspection
- Shop-head form; Hollow-End: soft bulge, no splitting.
Special but non-proprietary tooling
Needs more than a basic gun (special sockets, holders, or heads), but the tooling is available from multiple suppliers rather than locked to the fastener maker.
- Tool
- Torque wrench + special socket/holder
- Training
- Torque control critical for preload.
- How the install works
- Three-piece threaded assembly: rotating the bolt against the nut expands a stainless sleeve into the blind-side head; install torque directly sets clamp load (repeatable).
- Post-install inspection
- Torque verification; protrusion.
Proprietary installation systems
The fastener maker's own installation system is required for a conforming install. Budget for the tool, spares, and operator training, and treat tool availability as part of lead-time risk.
- Tool
- CherryLOCK hydroshift pulling system
- Training
- Tool-specific; Cherry training recommended.
- How the install works
- Requires the proprietary CherryLOCK hydroshift installation tool system: a real tooling commitment.
- Post-install inspection
- Flush-fractured stem; visible lock.
- Tool
- Monogram installation tool (hand or compact power)
- Training
- Specialty training, clamp-up control is critical on composite.
- How the install works
- Longer sleeve + corebolt form a very large blind-side upset at standard air pressure; installs and verifies entirely from one side.
- Post-install inspection
- Pintail break + protrusion; verify upset.
- Tool
- Hex driver (disposable hex-drive nut)
- Training
- Specialty; torque/clamp control on composite.
- How the install works
- Self-locking blind head with guaranteed ~20% minimum preload; spent hex-drive nut on the discarded pintail gives positive visual confirmation of a complete install.
- Post-install inspection
- Visual, nut sheared off = correct install.
- Tool
- Monogram installation tool
- Training
- Specialty.
- How the install works
- 360° radial expansion (.002-.006 in) uniform along the full grip increases fatigue life; tolerant of a loose .003 in hole: no costly close-tolerance prep.
- Post-install inspection
- Pintail break; protrusion.
- Tool
- Monogram installation tool
- Training
- Specialty.
- How the install works
- Only blind bolt offering full 1.5D bearing area equivalent to a solid bolt: closes the strength gap between blind and solid fasteners.
- Post-install inspection
- Pintail break; protrusion.
- Tool
- Push-and-pull install tool
- Training
- Tool-specific.
- How the install works
- Three-piece (bolt/nut/sleeve) with swaged mechanical lock; one BOM can replace ~4 conventional fasteners. HUCKCOMP variant tunes the footprint for composite.
- Post-install inspection
- Swage lock; stem break; protrusion.
- Tool
- Cherry Maxibolt installation tool (hand or pneumatic)
- Training
- Specialty; tool-specific for preload control.
- How the install works
- Push-pull tool forms an extended grip range with a flush-breaking stem; the Ti variant uses a shift-washer for composite clamp-up.
- Post-install inspection
- Stem flush-fracture; protrusion; visual lock.
- Tool
- Delta-Rad driver (three-lobe)
- Training
- Aerospace specialty; clamp-load control critical.
- How the install works
- Pin flutes plus automatic nut-lobe deformation form a positive mechanical lock at controlled torque, no FOD from a broken pintail.
- Post-install inspection
- Lobes deformed into flutes; preload verification.
- Tool
- Avdel 722 / 734 installation tool
- Training
- Tool-specific; straightforward.
- How the install works
- Two-piece pin + swaged collar; high, controlled clamp without relying on friction.
- Post-install inspection
- Collar lock engagement; visual tamper check.
- Tool
- Huck pin + collar swage tool
- Training
- Standard lockbolt procedure.
- How the install works
- Two-piece swage-lock; a flexible pin break accommodates a wide grip range, so one pin replaces several conventional fasteners.
- Post-install inspection
- Swage-lock form; collar break; preload gauge.
Tooling descriptions are family-level and datasheet-cited; specific gun and pulling-head model numbers vary by diameter and head style, so confirm the exact tool part number with the fastener manufacturer or your distributor before purchase. Not a certified process authority: install per the OEM process specification.
