8Pcs 5/8"-11 x 2-1/4" Cutting Edge Bolts for Snow Plow & Bucket Cutting Edge - Grader Blade Bolts Compatible with Tractor Bucket, Skid Steer Snow Plow, and Construction Machinery Accessories

What It Is

This is a set of 8 heavy-duty cutting edge bolts (5/8"-11 thread, 2-1/4" length) designed to secure grader blades, snow plow cutting edges, and bucket edges to tractors, skid steers, and construction machinery. They are not for lawn mower blades—despite the “Mower Blades” category—and are intended for ground-engaging attachments on compact or full-size equipment.

Fitment & Compatibility

Before buying, confirm three things:

• Thread size: Must be 5/8"-11 (coarse thread). Verify your existing bolts or equipment specs.
• Length: 2-1/4" from under the head to tip. Measure the depth of your blade/edge and mounting plate stack-up—bolts that are too short won’t grip, too long may bottom out or interfere.
• Head type: These are likely hex or carriage bolts with a square neck (check product images). Carriage-style requires a square hole in the blade; hex heads work in slotted or round holes.
• Brand/model: Not OEM-specific. Compatible with most standard cutting edges on skid steer buckets, tractor grader blades, and snow plows that use 5/8"-11 bolts. Not for mower decks, zero-turn blades, or residential lawn tractors.

Key Things to Know

• Quality concerns: 3.0 rating with only 2 reviews suggests limited feedback. Inspect threads for burrs and grade marking—these should be at least Grade 5 (or higher) for structural use.
• Installation: Moderate difficulty. You’ll need a torque wrench—typical spec is 90-110 ft-lbs for 5/8" Grade 5 bolts. Use anti-seize on threads to prevent galling.
• Common gotcha: Bolts may come with no lock washers or nuts. Check if your equipment uses nylock nuts or requires separate lock washers. Ordering a matching set of nuts is recommended.
• Fitment warning: If your blade uses countersunk holes (flush-mount), these bolts will not sit flush—they have a standard hex or square head that protrudes.

Should You Buy It

Buy this set if you need a budget-friendly, no-frills replacement for standard 5/8"-11 cutting edge bolts on a skid steer bucket, tractor grader blade, or snow plow, and you’re comfortable verifying length and head type yourself. Skip it if you require OEM-grade hardware, need countersunk bolts, or want a well-reviewed product—consider a known brand like John Deere, Caterpillar, or a local equipment dealer for critical applications.
