Benefits

A “nylon head” is a part for a brush cutter or string trimmer, with key specifications including its diameter (e.g., 109 mm, 130 mm), thread size and gender (e.g., M10 x 1.25 LH Female, M8 x 1.25 LH Male) for attachment to the tool, line capacity (e.g., dual line), line type (e.g., round, square), and feed mechanism (e.g., Tap & Go, Manual Feed, Easy Load). These specifications ensure compatibility with specific brush cutter models and facilitate easy replacement and loading of the nylon cutting line.

Key Specifications to Look For
Diameter:
The size of the head, such as 109 mm or 130 mm, which affects how it fits the brush cutter.
Thread Type:
The thread size (e.g., M10 x 1.25), gender (Male or Female), and direction (LH for Left Hand) that connects the head to the brush cutter’s shaft.
Line System:
Number of Lines: Most are dual-line, meaning they hold two strands of cutting line.
Line Size: The diameter of the nylon cutting line the head is designed to use, commonly in the range of 2.4 mm to 3.3 mm.
Feed Mechanism:
Tap & Go: Tapping the head on the ground extends the line automatically.
Easy Load: Allows for quicker loading of the line without complete disassembly.
Manual Feed: Requires manual feeding of the line.
Compatibility:
The specific brush cutter models the head is designed to fit, as attachments vary.
Material:
Often made of durable plastic or reinforced nylon to withstand impact and vegetation.
