Heavy-Duty Hex Lock Nut for Disc Mower Pressure Block Assembly SKU: Z17554

When pressure block lock nuts loosen or fail on disc mowers, cutting discs lose their proper tension and alignment, leading to vibration, uneven blade wear, and potentially dangerous disc wobble during operation. This heavy-duty hex lock nut restores the secure clamping force your pressure block assembly needs to keep cutting discs properly tensioned and balanced.

Key Benefits

• Self-locking design resists loosening under constant mower vibration and field conditions
• Heavy-duty construction withstands high stress loads from disc rotation and cutting forces
• Precise thread specifications ensure proper fit with pressure block assemblies
• Durable metal construction provides long-lasting performance in demanding farm environments

A loose or missing pressure block nut compromises disc alignment and creates safety hazards during mowing operations. With over 55 years of farm equipment expertise, S&H Parts understands the critical role this small component plays in keeping your disc mower running safely and efficiently.
