Westward 54TU50 SAE Hex Key
The Westward 54TU50 is a plain hex key built from alloy steel with a black oxide finish. It suits technicians who need a 5/8 inch SAE tip for HVAC control work. The tool is new and ready for immediate use in maintenance or repair tasks. No insulation or tether points are included.
Two-Tip Configuration for Access
This key provides two tips on a single piece, giving both a long arm of 6 15/64 inches and a short arm of 5/8 inch. The longer reach helps with recessed fasteners while the shorter end fits tight clearances. Both tips share the same 5/8 inch size so no adapter is needed. The plain design keeps the profile slim for crowded panels.
Simple Hand Installation
Installation is straightforward: select the arm that fits the access and turn by hand or with light leverage. The alloy steel resists rounding when the fastener is clean and properly seated. Problems arise if the tip is worn or the bolt is corroded, which can cause slippage. The key has no tether hole so secure storage is the user's responsibility.

Questions about this item
Will the black-oxide coating on the 54TU50 hex key wear off and require replacement?
The black-oxide finish protects the alloy steel from surface corrosion; it will gradually wear with heavy use but the tool remains functional without recoating.
What stops the 5/8-inch tip from rounding off first during sustained torque?
The alloy-steel construction resists deformation, yet the 5/8-inch short arm gives the least leverage, so that tip reaches its torque limit before the long arm.
Does the 6 15/64-inch long arm transmit heat or vibration during all-day HVAC work?
The solid alloy-steel body conducts some heat from hot fasteners and transmits vibration directly to the hand; no insulation or damping is present.
