What this is
Four replacement chains for Worx’s 20V 5” pruning saws: the WG325 (Nitro) and the WG324, including their .X kit versions. Both manuals list Worx chain WA0142 on bar WA0151: 5” (12 cm) bar, 0.3” (7.6 mm) pitch, .043” gauge, 28 drive links. This pack is the same size.
A pitch of its own
Worx gives this chain’s pitch as 0.3”, which differs from the 3/8” low-profile chains on most 6” and 8” pruning saws. A chain from another brand’s mini saw won’t match just because the length looks similar. Match all three numbers: 0.3” pitch, .043” gauge, 28 drive links.
Fitting it
The WG325 has tool-free tensioning through the knob on the housing cover, and an oil tank you fill with bar and chain oil.
