Nuts & Bolts

For hammer mills and grinding equipment, selecting the right nuts and bolts is crucial for durability, reliability, and ease of maintenance. Here are the best types for various applications:

Recommended Nuts for grinding equipment:

• Heavy Hex Nuts – Thicker and stronger than standard hex nuts, providing better load-bearing capacity for high-impact areas.
• Lock Nuts (Nyloc or Jam Nuts) – Used to prevent loosening due to vibration, making them ideal for securing hammer rods and wear plates.
• Flange Nuts – Have a built-in washer to distribute load evenly, reducing stress on grinding equipment components.
• Square Nuts – Offer a larger surface area for gripping, often used with carriage bolts for securing plates and screens.

Recommended Bolts for grinding equipment:

• Hex Head Bolts – Standard heavy-duty bolts commonly used for securing grinding equipment components like screens, grates, and wear plates.
• Carriage Bolts – Feature a smooth, rounded head with a square neck to prevent turning, ideal for fastening wear plates and back plates.
• Plow Bolts – Countersunk bolts with a flat or dome head, excellent for securing high-wear components like hammers and screens while minimizing surface obstruction.
• Grade 8 Bolts – High-strength bolts designed for extreme impact and vibration resistance, ideal for heavy-duty grinding equipment applications.
• Stainless Steel Bolts – Best for applications requiring corrosion resistance, such as mills used in damp or acidic environments.
