The Multiquip 503113 Countersunk Screw 1/4-20 x 3/4 is a genuine OEM fastener designed for FS1 series concrete saws. As a direct OEM replacement, 503113 delivers the correct thread pitch, head geometry, and material grade to match the original hardware specification. Multiquip sources these fasteners to the same standards as the screws installed at the factory, so fitment on FS1 concrete saws is exact. Whether you are replacing a damaged fastener or restocking your service kit, this is the correct part to order.
Key Features
- Correct Thread Specification: — 1/4-20 UNC thread form matches the tapped receiving points on FS1 concrete saw assemblies for a flush, secure installation.
- Countersunk Head Profile: — Flat countersunk head sits flush with the panel or guard surface, maintaining clearance and preventing snagging during saw operation.
- Genuine OEM Hardware: — Sourced directly from Multiquip, this fastener meets the same material and dimensional standards as the original production screw.
- FS1 Concrete Saw Fitment: — Confirmed for FS1 series concrete saws; verify your model and fastener location before ordering to ensure this is the correct application.
- Structural Integrity Under Vibration: — A correctly sized and torqued screw prevents guard, cover, or component movement during cutting — a loose or wrong-spec fastener can lead to misalignment or component damage during high-vibration saw use.
A countersunk screw is a flat-head fastener designed so its head sits flush with or below the surface of the material it secures. In concrete saw applications, these screws are commonly used to fasten guards, covers, and structural panels where a protruding fastener head would create interference or a safety hazard. When a screw strips, shears, or goes missing, the component it secures can shift or vibrate loose during cutting — replacing it promptly with the correct OEM specification fastener restores the integrity of the assembly.
