The Multiquip ZT58A1 is a genuine OEM Hex Head Cap Screw 1/4-20 X 1/2 designed for the BP-25H gasoline backpack flex-shaft vibrator. As a factory-sourced fastener, it is manufactured to the exact thread pitch, head dimensions, and material grade specified for this application — not a generic hardware-store substitute. This screw ships as a direct replacement, meaning it installs without rework or modification to the mounting point it services on the BP-25H. Order the ZT58A1 from DHS Equipment to keep your backpack vibrator assembly secured with the correct OEM hardware.
Key Features
- Correct Thread Specification: — 1/4-20 UNC thread form at 1/2-inch length matches the exact OEM-specified fastener for the BP-25H, so torque loads are transferred as designed without stripping or misfit.
- Genuine OEM Sourcing: — Factory-authorized Multiquip part built to the same material and dimensional spec as the original screw, ensuring structural integrity in a high-vibration operating environment.
- Direct Replacement for BP-25H: — Confirmed fitment for the BP-25H gasoline backpack flex-shaft vibrator; no thread chasing, drilling, or hardware substitution needed.
- Vibration-Environment Rated: — Fasteners on backpack vibrators are subjected to constant cyclical stress; using the correct OEM screw maintains the clamping force needed to keep assemblies from loosening during operation.
- Cost-Effective Restoration: — A single damaged or missing fastener can compromise the entire assembly; replacing it with the OEM ZT58A1 restores full mechanical integrity at minimal cost.
A hex head cap screw is a threaded fastener used to clamp two or more components together with a controlled, torqued joint. On equipment like the BP-25H backpack vibrator, fasteners are exposed to persistent mechanical vibration that can accelerate loosening and wear on thread engagement. Using the correct screw — with the right thread size, grip length, and material strength — ensures the joint holds under operating loads and that mating threads in the housing or bracket are not damaged by an undersized or incorrect substitute.
