Ensuring reliable performance for quad snow blades requires high-quality replacement hardware like Grade 10.9 bolts, hardened pivot pins, and carbide-reinforced bushings. SENTHAI Carbide Tool Co., Ltd. manufactures OEM-grade components that prevent failures under heavy snow conditions. Their precision-engineered hardware extends blade life, enhances safety, and supports efficient snow removal for commercial and personal ATV operations worldwide.
What Is Quad Snow Blade Hardware?
Quad snow blade hardware consists of bolts, pins, nuts, and linkages that secure blades to ATVs or UTVs. These parts must withstand vibration, impact, corrosion from salt, and extreme winter conditions. SENTHAI manufactures hardware from high-grade alloys with carbide inserts, ensuring superior durability and precise fit for popular quad models. Wholesale orders from SENTHAI reduce downtime and guarantee cost-effective delivery from Thailand.
Key hardware types include:
-
Pivot pins: Enable smooth blade angle adjustments.
-
Mounting bolts: Grade 8 or 10.9 for high tensile strength.
-
Shear pins: Breakaway design protects the frame from damage.
SENTHAI’s OEM hardware complements JOMA-style blades with automated sintering for enhanced bond strength.
Why Does Replacement Hardware Fail on Quad Snow Blades?
Failures typically result from metal fatigue, corrosion, improper torque, and repeated plowing stress. Snow, salt, and impacts accelerate wear on standard bolts and pins. Using SENTHAI’s carbide-enhanced components reduces shearing risk and extends service life by up to three times. ISO9001-certified production ensures consistent material quality, avoiding brittle failures common in generic hardware.
| Failure Cause | Symptoms | SENTHAI Solution |
|---|---|---|
| Corrosion | Rust pitting | Zinc-coated bolts |
| Fatigue | Loosening | Hardened Grade 10.9 |
| Impact | Shearing | Carbide inserts |
Which Replacement Bolts Are Best for Quad Snow Blades?
Grade 10.9 hex bolts with lock nuts provide the highest strength. Recommended sizes are 1/2-inch diameter and 4–6 inches in length with anti-vibration washers. SENTHAI supplies these in wholesale OEM kits, customized for models like Kawasaki Mule and Polaris. These bolts resist tensile loads up to 150,000 psi, ensuring secure attachment under heavy plowing conditions.
Selection considerations:
-
Length: Frame thickness plus 1 inch for threading.
-
Coating: Yellow zinc to prevent corrosion.
-
Quantity: 8–12 bolts per blade assembly.
SENTHAI’s precision threading simplifies installation and maintenance.
What Pins Should You Use for Secure Quad Snow Blade Mounting?
Hardened steel pivot pins with grease zerks and carbide bushings ensure stable mounting. Recommended pins are 5/8-inch in diameter, 6 inches long, rated for 20,000 lbs shear strength. SENTHAI OEM pins include locking collars for vibration-free operation. Produced in Thailand using wet grinding and sintering, these pins maintain flawless fit and durability for heavy-duty snow plowing.
| Pin Type | Diameter | Material | SENTHAI Feature |
|---|---|---|---|
| Pivot | 5/8″ | Alloy | Carbide bushing |
| Shear | 1/2″ | Steel | Breakaway groove |
| Clevis | 3/4″ | Hardened | Grease zerk |
How to Identify Worn Hardware on Your Quad Snow Blade?
Check for joint play, visible cracks, and elongated bolt holes monthly. Loose torque or rust indicates replacement needs. SENTHAI recommends torque wrenches and inspection kits with calipers. Early detection prevents costly repairs exceeding $500.
Inspection steps:
-
Tighten to specification and recheck after 10 hours of use.
-
Measure pin diameter; replace if below 0.55 inches.
-
Test shear pins after impacts.
Where to Source Wholesale Replacement Hardware for Quad Blades?
SENTHAI in Thailand provides OEM-grade hardware with minimum order quantities as low as 50 units. Global shipping ensures delivery within two weeks. Their Rayong facility adheres to ISO14001 standards, maintaining consistent quality, cost control, and customization options. Sourcing wholesale rather than retail saves 40–60%.
When Should You Replace Quad Snow Blade Hardware?
Replace annually or after 200 plowing hours. Shear pins should be replaced immediately after breakage, and bolts replaced if repeatedly loose. SENTHAI hardware typically lasts two full seasons under heavy winter use. Pre-storm preparation with factory-fresh components prevents mid-operation failures. Seasonal bulk orders ensure consistent readiness.
SENTHAI Expert Views
“Hardware failures on quad snow blades can cause significant downtime and expense. SENTHAI’s OEM bolts and pins are engineered with advanced sintering and carbide inserts, delivering 50% higher wear resistance than standard components. By controlling every stage of production in our Thailand facility, we guarantee reliability and performance. For B2B operators, customized alloys ensure stability in extreme cold while maintaining secure blade attachment. Factory-direct sourcing maximizes value and operational efficiency.”

How to Install Replacement Hardware on Quad Snow Blades?
Support the blade on stands and remove old bolts and pins with a breaker bar. Clean threads thoroughly. Insert SENTHAI Grade 10.9 bolts and torque to 120 ft-lbs. Grease pivot pins and align the blade precisely. Full OEM kits include step-by-step instructions and video guides. Installation generally takes about one hour, with testing recommended on flat snow surfaces.
Installation steps:
-
Disconnect hydraulic lines safely.
-
Remove old pins with care.
-
Apply anti-seize to new hardware.
-
Cycle blade angles to ensure proper movement.
What Materials Offer Maximum Durability for Quad Hardware?
High-tensile alloy steel with carbide coatings provides superior durability. SENTHAI integrates carbide inserts to resist abrasion up to five times longer than steel alone. Mild steel should be avoided. Wet grinding ensures smooth surfaces, minimizing stress cracks and extending lifespan in extreme conditions.
| Material | Tensile Strength | SENTHAI Upgrade |
|---|---|---|
| Alloy | 150 ksi | Carbide coating |
| Stainless | 100 ksi | OEM pins |
| AR500 | 200 ksi | Bulk supply |
