The Bomag 07850313 Parker Screw is a genuine OEM fastener designed for Bomag BW-series single drum rollers, BW-series tandem rollers, and BM-series cold milling machines. Sourced directly from Bomag, this Parker Screw matches the original specification exactly, ensuring a correct, secure fit without adaptation. Compatible models include the BW 145 D-3, BW 145 DH-3, BW 145 PDH-3, BW 170 AD, BW 174 AC, BW 174 AD, BW 180 AD, BW 184 AD, C 825 C, BM 500/15, BM 600/15, BM 1000/35, BM 1200/35, BM 1300/35, and their generation variants — making part number 07850313 a versatile fastener across a broad range of Bomag equipment. Using the correct OEM screw protects the integrity of the assembly it secures and helps prevent loosening, stripping, or premature wear at the fastening point.
Key Features
- OEM Thread and Dimensional Accuracy — manufactured to Bomag's exact thread pitch, head geometry, and material grade, so the fastener engages correctly without risk of cross-threading or undertorque
- Direct Drop-In Replacement — engineered to the same specification as the original Parker Screw, fitting the existing threaded bore or mounting point with no rework required
- Broad Bomag Compatibility — fits BW 145, BW 170, BW 174, BW 180, and BW 184 single drum and tandem rollers, as well as BM 500/15, BM 600/15, BM 1000/35, BM 1200/35, and BM 1300/35 cold milling machines, including EU-Flex, T4f, T4i, Stage V, and -2 generation variants
- Secure Clamping Under Vibration — a correctly specified Parker Screw maintains clamping force under the continuous vibration and load cycles that rollers and milling machines generate; an incorrect or worn fastener risks joint failure and component damage
- Genuine Bomag Part — supplied as an authentic Bomag component, giving you confidence that part number 07850313 is the exact item called out in the Bomag parts catalog for your machine
A Parker Screw is a self-tapping or thread-forming fastener used to securely join components within the machine's assembly — typically panels, housings, brackets, or hydraulic and electrical covers. It creates its own mating thread on installation, which means the correct diameter, thread form, and drive type are critical to achieving the intended clamping load. When a Parker Screw is stripped, missing, or substituted with an incorrect size, the joint can work loose under machine vibration, leading to rattling components, misalignment, or unprotected assemblies. Replacing it with the correct Bomag OEM screw restores the fastening point to its original holding strength.
