The Husqvarna 506195801 Pin Retaining Screw is a genuine OEM component designed for the K40 power cutter. As a factory-original part, it meets Husqvarna's exact specifications for material grade, thread form, and dimensional tolerancing — ensuring a proper, secure fit within the assembly it secures. This screw installs directly as a like-for-like replacement, with no adaptation needed to match the original mounting configuration on the K40. DHS Equipment supplies this part to help keep your equipment running at full performance.
Key Features
- Genuine OEM Thread and Material Specification — manufactured to Husqvarna's exact grade and dimensional tolerances, ensuring the screw engages correctly and holds under operational load without risk of backing out or stripping.
- Direct Drop-In Replacement — engineered to match the original fastener profile on the K40, so the part installs cleanly into the existing mounting point without rework or adaptation.
- Confirmed K40 Fitment — verified for the Husqvarna K40 power cutter, so you can cross-reference part number 506195801 against your parts diagram with confidence.
- Structural Integrity Restored — a worn, stripped, or missing retaining screw can allow pins and internal components to shift under vibration, leading to misalignment or accelerated wear; replacing it promptly restores correct assembly retention.
- Operational Safety — on a handheld power cutter, fastener integrity is a safety-critical concern; using the correct OEM screw ensures the retained component stays positively located during cutting operation.
A pin retaining screw is a fastener that locks a pin, shaft, or internal component in its correct position within a mechanical assembly. On a handheld power cutter like the K40, this type of screw prevents lateral or rotational movement of the retained pin under the vibration and load generated during cutting. When the screw becomes stripped, damaged, or lost, the pin it secures can shift out of position, causing misalignment, increased wear on adjacent components, or an unsafe operating condition. Replacing it with the correct OEM part restores the integrity of the assembly and returns the machine to proper working order.
