BOSS HDW01729 – 1/2” F436 Hard Washer
The Genuine BOSS HDW01729 is a high-performance 1/2″ Hardened Flat Washer designed to meet the rigorous demands of professional snow and ice management. Engineered to ASTM F436 standards, this washer is a critical component for distributing high-tension loads in structural assemblies, ensuring your BOSS Snowplow or Spreader maintains its integrity under extreme conditions.
Precision Engineering & Technical Specifications
The HDW01729 is specifically manufactured for use with high-strength fasteners like Grade 5 and Grade 8 bolts. As an F436 Hardened Washer, it is heat-treated to provide superior hardness and compression resistance, preventing the “cupping” or deformation that standard washers experience under high torque.
To survive the corrosive environment of winter roads, this washer features a premium Yellow Zinc (YZN) plating. This industrial finish provides an exceptional barrier against road salt, brine, and constant moisture, ensuring that your hardware remains reliable and easy to service for years to come.
Versatile Application Across BOSS Systems
This essential piece of hardware is used across various platforms in the BOSS Snowplow parts lineup, including:
-
BOSS Undercarriage Mounts: A key component in vehicle-specific mounting kits to secure the push beam to the truck frame.
-
BOSS Power-V and Straight Blade Assemblies: Used in structural joints where 1/2″ bolts (such as the HDW01728) require high-strength load distribution.
-
BOSS VBX & TGS Spreaders: Integral to the assembly of hopper supports and motor mounting frames.
Why Choose Genuine BOSS OEM Hardware?
