Working Mechanism

  • Place one of the ends inside a fastener with a hexagonal key and turn it.
  • Turn the key for rotating the fastener to tighten or loosen it.
  • For tightening, rotate clockwise. For removing or loosening, turn it counter-clockwise.

Features

  • PROTO hex key sets feature heat-treated alloy steel construction with rust-resistant black oxide finish for prolonged use.
  • They come with plain, L-shaped, fold-up & ergonomic T-handles for convenient fastening.
  • The folding hex key sets (such as J4978) comprise multiple keys attached to one handle.
  • Keys with tips having a hex ball end allow fasteners access to hard-to-reach areas from multiple angles.
  • Selected models are L-shaped and have two arms of unequal length.
  • They allow both Metric & SAE measurement and are available in packs of 5, 6, 7, 9, 11, 13, 14, 15 & 18 pieces.
  • These sets are supplied in a metal storage box or moulded plastic holder.

Frequently Asked Questions

What is the difference between T-shaped and L-shaped keys?

T-shaped hex key sets (unlike L-shaped keys) feature one long arm with a drive tip at the end, along with a handle for delivering more torque when rotating fasteners.

What is the difference between long end & short end handle keys?

Rotating a long end handle key delivers more torque on the fastener, as compared to using a short end handle key.

How do you maintain hex key sets?

  • Protect keys from rust formation.
  • Store in a dry and clean place.
  • Wipe and lubricate after each use.
