Adjustment screw for the chain tensioner of STIHL petrol chainsaws of the MS070 and MS090 series

Are you experiencing problems with the chain tension on your large, classic STIHL chainsaw? Are the adjusting screws damaged, or is the guide bar jammed? The chain tensioner is a crucial component for optimal tension; damage can compromise cutting accuracy and safety. This high-quality chain tensioner adjusting screw is specifically designed for large, classic chainsaws such as the STIHL 070, 090, MS070, and MS090, allowing for precise guide bar adjustment. Chain tensioner function: The chain tensioner (also called an adjusting screw) is used to adjust the chain tension. Correct tension ensures smooth chain operation on the guide bar and prevents excessive play (risk of the chain derailing) as well as over-tensioning (increased wear and power loss). Key features: Authentic replica: The adjusting screw precisely matches the diameter, length, pitch, and thread direction of the original chain tensioning screw and fits perfectly onto the guide bar adjusting nut of your chainsaw for precise adjustment after installation. Reinforced Adjustment Head: The screw head (the part that contacts the guide bar) is reinforced with the adjustment pin for a perfect fit. This ensures even force distribution during adjustment and reduces the risk of wear and deformation. Ergonomic Rotary Knob (on some models): Some sets include a large, comfortable adjustment knob that is easy to operate, even with gloves, for quick and easy chain tension adjustment. Anti-Loosening System: Thrust washers or locking systems effectively prevent loosening due to vibration, ensuring a secure hold on the guide bar.
