SP-7570 Guide Bar Nut for Chainsaws 2500/4500/5200/5800 — Secure Bar and Frame Fastening

SP-7570 is a standard guide bar nut, also referred to as a frame nut, designed for chainsaws with engine capacities of 25–58cc, including models 2500, 4500, 5200, and 5800. It fastens the clutch cover and the guide bar holder plate, keeping the bar stable during use.

Why a Good Bar Nut Matters

The bar nut is a critical safety component. A loose or worn nut may cause the bar to shift, resulting in chain slack or accidents. The SP-7570 ensures firm bar attachment, reduces vibrations, and supports long-term reliable performance.

Advantages of the SP-7570

• Standard M8 thread with wide pitch
• Wide contact surface for secure tightening
• Durable alloy with corrosion-resistant coating
• Fits most Chinese chainsaws
• Ideal for household and semi-professional use

Check the stud thread size on your saw before purchasing. SP-7570 fits most saws with a classic side cover mount system.
