Description
Overview:
This grub screw is a genuine Terex OEM fastening for securing components inside the coupling hub on compacting equipment. Made from high‐grade hardened steel with a protective black finish, it delivers a tight, flush fit that resists loosening under vibration. It is designed for Terex/Benford/Mecalac rollers and rammers, with direct application on the vibrator leg assembly of the TV800 and TV900. The headless, hex socket design allows the screw to sit below the surface, protecting against snagging and helping keep rotating parts aligned. Built for tough site conditions, it supports reliable operation and helps reduce downtime during routine maintenance and repairs across plant, hire, and contractor fleets.
Key Features:
- Genuine Terex OEM part for assured fit and reliable performance
- High‐grade, hardened steel construction for strength in high‐vibration use
- Protective black finish to help resist corrosion in wet or dusty conditions
- Headless, internal hex drive for a flush, secure fit within the hub
- Precision threads for firm clamping of shafts, hubs, collars, and couplings
- Stable fastening helps maintain vibrator leg alignment and smooth roller operation
- Straightforward to install and remove with a standard hex key, aiding quick servicing
- Built for heavy-duty site work and frequent maintenance cycles
Typical Applications:
Used to lock components in the coupling hub and vibrator leg assembly on tandem rollers, helping prevent movement of shafts, collars, and gears under load. Common in maintenance and rebuilds of Terex/Benford/Mecalac compactors and rollers on construction sites, highways, utilities, and plant hire fleets where dependable retention and easy servicing are required.
