Application Context

Grub screws in this assortment excel where standard bolts cannot protrude beyond the component surface:

• Precision machinery assembly: Setting collars, pulley locks, bearing preload
• Tool assembly: Securing components on hand tools, pneumatic tools, impact wrenches
• Equipment maintenance: Shaft locks, adjustment screws in gauges and instruments
• Device repair: Electronics enclosures, control panel mounting, securing trim components

The coarse/fine-thread split ensures compatibility with both standard metric threads and applications requiring finer pitch engagement (pressure-sensitive assemblies, thread-locking applications).

Bottom Line

Your customers see a complete solution; you stock one product that addresses dozens of real-world fastening challenges. The hex socket design, steel construction, and dual-thread offering position this firmly in the professional tier—justifying margin while delivering genuine value to end users who recognize quality assortment depth.
