The Multiquip ZT58A3 Hex Head Cap Screw 1/4-20 X 3/4 is a genuine OEM fastener designed for the BP-25H gasoline backpack flex-shaft vibrator. As an OEM component, it is manufactured to the exact thread specification and dimensional standard called out in the original equipment design, ensuring a correct fit at every fastening point where this screw is used. Whether you are completing a service rebuild or replacing hardware lost during field maintenance, the ZT58A3 matches the original fastener spec without guesswork. Confirm your model code against the BP-25H parts diagram before ordering to ensure this is the correct position for your repair.
Key Features
- OEM Thread Accuracy — Manufactured to the exact 1/4-20 thread pitch and 3/4-inch length specification, so there is no risk of cross-threading or improper clamping load at installation.
- Hex Drive Configuration — Standard hex head format accepts common wrenches and sockets already on your service bench, making installation straightforward in tight assembly areas.
- Direct OEM Replacement — Sourced as a genuine Multiquip part under part number ZT58A3, matching the hardware spec originally built into the BP-25H backpack vibrator.
- Verified Fitment for BP-25H — Confirmed fitment for the BP-25H gasoline backpack flex-shaft vibrator; cross-reference your parts diagram to identify the correct fastener position.
- Structural Integrity at the Fastening Point — A worn, stripped, or incorrect fastener in a vibrating assembly can allow components to loosen under continuous oscillation; using the correct OEM spec screw maintains clamping force throughout operation.
A hex head cap screw is a threaded fastener used to clamp two or more components together within an assembly. In a backpack concrete vibrator like the BP-25H, fasteners are subjected to constant vibration during operation, which places ongoing stress on thread engagement and clamping force. Using a fastener with the correct thread form, diameter, and length — as the Multiquip ZT58A3 provides — ensures that structural connections within the vibrator assembly remain secure and do not work loose during use. A missing or incorrect fastener in a vibrating assembly can lead to component movement, accelerated wear, or failure of adjacent parts.
