Key Features
- Genuine OEM Fastener Grade — Black steel construction meets Husqvarna's specified hardness and torque requirements for this fastener position, preventing stripping or premature loosening under operational vibration.
- Shouldered Hex Drive Design — The shoulder profile provides a positive mechanical stop during installation, allowing the screw to seat consistently at the correct depth without over-tightening.
- Direct Compatibility — Engineered specifically for the SoffCut2500 and SoffCut5000 early entry saws, with thread size and shoulder dimensions matched to the original Husqvarna assembly.
- Structural Integrity Restored — A correctly installed screw of the right specification keeps adjoining components properly aligned and secured, preventing movement that can lead to accelerated wear of surrounding parts.
- Verified OEM Part Number — Ordering by part number this part ensures you receive the exact Husqvarna-sourced fastener, not an approximation — critical when thread pitch and shoulder length must be precise.
A shoulder hex set screw serves as a precision fastener that locates and locks a component at a fixed, repeatable depth within an assembly. The shouldered section acts as a mechanical stop, controlling insertion depth while the hex socket drive allows controlled torque application in tight spaces. When this type of fastener wears, strips, or goes missing, the components it secures can shift under load or vibration, leading to misalignment, accelerated wear on surrounding parts, or loss of function in the affected assembly. Using the correct OEM specification screw restores the original clamping force and dimensional accuracy the machine was designed around.
