Description
Hydraulic lockbolt hoses leak messy fluid across production floors and kink during structural commercial trailer assembly. The Milwaukee M18 FUEL 1/4inch Lockbolt tool bare tool with protective boot installs heavy structural fasteners without hydraulic pumps. This eighteen-volt tool pulls three-sixteenths and one-quarter-inch structural lockbolts and blind rivets. Misaligning the pulling collar on grooved pins causes jaw slippage and premature jaw tooth wear.
An internal brushless motor powers an all-metal planetary gear drive linked to a case-hardened recirculating ball screw assembly. Heavy-duty thrust needle roller bearings absorb twenty kilonewtons of continuous axial pulling force without race spalling. The nose housing is cast from ductile iron to withstand severe mechanical snap-back shock upon fastener pin break. Premium pulling collets are machined from shock-resistant S7 tool steel to prevent tooth fractures.
Structural Lockbolt Hardware Matrix
High-tensile pulling mechanisms install structural Huck-style lockbolts flush without dragging heavy hydraulic pump hoses through trailer frames. The custom rubber boot protects structural painted surfaces from contact scratches during high-volume assembly passes.
- Eighteen-volt brushless motor core delivers forty-five hundred pounds of tensile pulling force for structural fastening
- Protective rubber boot cushions incidental tool contact against finished vehicle paint and structural panels
- Dual-jaw architecture installs structural blind rivets and lockbolt collars from three-sixteenths to one-quarter-inch diameter
- Recirculating ball screw mechanism eliminates messy hydraulic fluid leaks and blown pneumatic cylinder seals
- ONE-KEY tool tracking allows cycle counting, inventory management, and digital tool security lockouts
- Tool-free nosepiece access permits fast clearing of sheared fastener pins and rapid jaw cleaning
- Clear rear collection bottle captures sheared pintails to prevent shop floor slip and trip hazards
Tensile Pull Bench Telemetry
Testing registers a sustained tensile pulling force output of 4,500 pounds with a long 1.18-inch axial stroke length. Dynamic pneumatic comparison matches a heavy blind riveter consuming 7.8 CFM at 90 PSI dynamic through three-eighths-inch lines. Sound level meters record 81 dBA at operator ear level upon structural pin break. Ball screw drive housing temperatures rise twenty-six degrees Fahrenheit above ambient across one hundred continuous lockbolt cycles. Dynamic cycle duration completes full fastener install in 1.8 seconds.
Fleet Service Application Filter
Do not assign this heavy structural lockbolt puller to thin aluminum sheet metal pop riveting or delicate electronics chassis assembly. Massive pulling tonnage will distort thin sheet metal and pull small rivet heads straight through soft panels. Operating with uncleaned jaw teeth causes jaw slip that strips the pull grooves off structural pins.
- Disassemble the front nose casing and clean jaw teeth using a brass wire brush every five hundred cycles.
- Apply high-pressure molybdenum grease to the outer jaw bevel surface during routine cleaning intervals.
- Empty the clear rear pintail collection canister before spent pins pack tight inside the internal guide tube.
