The Multiquip EM915001 1/4-20 X 1/2 HCS YZ8 is a genuine OEM hex cap screw designed for SP4 flat saws and SP6457 pavement saws. As a factory-sourced fastener, EM915001 matches the original thread pitch, head dimensions, and zinc yellow chromate coating specified for these machines. Sourcing the correct OEM hardware ensures proper torque retention and material compatibility at every reassembly point. DHS Equipment supplies this part direct so you can get back to work without improvising with off-spec hardware.
Key Features
- OEM-Grade Zinc Yellow Chromate Finish — The YZ8 designation confirms a zinc yellow chromate (Grade 8) coating that delivers corrosion resistance suited to outdoor cutting environments where moisture and concrete slurry are constant factors.
- Correct Thread Specification — 1/4-20 UNC threading and 1/2-inch length match the original fastener profile exactly, seating flush and threading true without rework or chasing.
- Confirmed Fitment for SP4 and SP6457 — Verified for use on Multiquip SP4 flat saws and SP6457 pavement saws, so you can order with confidence that this part is the right call for your machine.
- Grade 8 Strength Rating — Higher tensile strength than standard hardware-store equivalents, important wherever fasteners are subject to vibration loads from blade operation and engine output.
- Fuel and Fluid System Safe — Zinc yellow chromate plating resists degradation from fuel, cutting water, and general jobsite chemical exposure, maintaining clamp load over time.
A hex cap screw like the EM915001 may be a small component, but fastener quality has a direct impact on structural integrity throughout the saw assembly. Vibration generated during cutting places cyclic stress on every threaded connection, and an underspec or worn fastener can back out, lose clamp force, or fail entirely — creating loose guards, misaligned components, or unsafe operating conditions. Using the correct Grade 8, properly coated OEM fastener ensures the joint holds to its designed torque value and stays there through the full service interval.
