Plow bolts and nuts secure wear plates, cutting edges, and ground engaging tools — and under-torqued or worn fasteners allow movement that rapidly destroys both the bolt and the wear plate. This plow bolt +nut 1 1/4″ * 4.53 is manufactured to correct grade and dimensions for secure installation.

Why Choose This Plow Bolt +NUT 1 1/4″ * 4.53
– Correct head profile for flush or recessed fitment in countersunk wear plate holes
– Nut configuration matched to OEM torque specification and locking requirement
– Thread form and pitch matched to OEM for correct installation without cross-threading

Heavy-Duty Construction
This plow bolt +nut 1 1/4″ * 4.53 is manufactured using high-tensile steel: Grade 8.8 or 10.9 depending on application (confirm when ordering). Hardened nut for correct tension retention under vibration. Zinc-plated or untreated as required for the application environment. Designed to withstand vibration, impact loads, and harsh operating environments commonly found in construction, quarry, mining, and earthmoving applications. Precision manufacturing helps ensure correct fitment and long service life.

Applications
Suitable for a wide range of heavy equipment and undercarriage systems including:
– Excavators
– Dozers
– Loaders
– Track roller assemblies
– Earthmoving machinery undercarriage components

Maintenance Recommendations
– Torque to OEM specification
– Use thread lubricant on installation to achieve correct clamp load from the torque applied
– Re-torque after first 8 operating hours; vibration bedding reduces initial clamp load
