PRODUCT DESCRIPTION

SL90-314-7500

  • Precision Alignment Sleeve - Guides the washer concentrically over the fastener shank, eliminating off-center seating that can lead to uneven clamp loads.

  • Durable Hardened Steel Construction - Machined from high-strength alloy steel and heat-treated to resist wear, ensuring long service life under frequent use.

  • Ergonomic Handle Design - Contoured for a comfortable grip, reducing technician fatigue during repetitive installation tasks on production lines or in hangars.

  • Quick-Change Washer Inserts - Removable internal guides support multiple washer sizes, allowing rapid changeover between fastener diameters.

  • Proper seating of self-locking washers on wing-to-fuselage and empennage structural bolts.

  • Installation of lockwashers under nut heads in landing-gear and flight-control surface assemblies.

  • Controlled assembly of avionics rack fasteners requiring uniform clamp load.

  • Mandrel-free seating of washers on high-cycle fatigue-critical joints.

  • How does this tool maintain torque accuracy?

The integrated torque-adapter interface transmits only axial load to the wrench, preventing side forces that can skew torque readings.

  • Does the tool require calibration?

No calibration is needed, but inspect the guide sleeve and inserts routinely for wear to ensure precise washer seating.

  • What maintenance does the tool require?

Clean debris from the alignment sleeve, lightly lubricate moving parts, and inspect hardened surfaces for nicks or deformation.
