Key Features
- Genuine OEM Construction — manufactured to Husqvarna's original material and dimensional specifications, ensuring the correct hardness and tension retention that a lock washer must maintain under repeated torque loading
- Direct Hardware Replacement — installs into the original fastener position without modification, restoring the clamping integrity of the assembly exactly as designed
- Broad HTC Series Compatibility — confirmed fit for HTC80, HTCD80, HTCGL400, and HTC80iD floor grinders and dust and slurry equipment, covering multiple variants within the HTC product line
- Prevents Fastener Loosening — a correctly seated lock washer resists vibration-induced loosening that is common in grinder and surface prep equipment during prolonged operation; a worn or missing lock washer can allow critical fasteners to back out and compromise the assembly
- Fastener Safety — in rotating-equipment assemblies, a properly functioning lock washer is a key safeguard against unintended fastener movement, helping maintain the structural integrity of the machine during operation
A lock washer is a hardened hardware component placed under a fastener to prevent it from loosening due to vibration, rotation, or dynamic loads. In floor grinding and surface prep equipment like the HTC series, vibration levels are high and continuous, making secure fastener retention essential to keeping assemblies tight and aligned. When a lock washer fails, deforms, or goes missing, the fastener it secures can gradually back out, leading to play in the assembly, accelerated wear on surrounding components, or a loss of structural integrity that affects both performance and safe operation.
