Hex Jam Nuts / Thin Hex Nuts (SAE J482 / SAE J995 Gr. 2) – Low Profile Locking Solution – Manufacturer Direct

High-Quality Hex Jam Nuts (Thin Nuts): The Essential Low-Profile Locking Solution

At Handan Bolt, we manufacture precision-engineered Hex Jam Nuts, also widely known as Thin Hex Nuts or Low Profile Nuts. Produced in our world-class facility in Yongnian, China, these fasteners are designed specifically for applications where space is limited or where a secondary locking mechanism is required. Our Hex Jam Nuts strictly adhere to the SAE J482 dimensional standard and SAE J995 Grade 2 material specifications, ensuring reliability and performance for our global clients.

What is a Hex Jam Nut?

A Jam Nut (Read more on Wikipedia) is a thinner version of a standard hex nut. While a standard nut provides the primary clamping force, a jam nut is typically used in one of two ways:

1. As a Locking Device: It is “jammed” against a standard nut to prevent it from loosening due to vibration.
2. In Tight Spaces: It is used as a standalone fastener in applications where a full-height hex nut simply will not fit.

Technical Excellence: SAE J482 & SAE J995 Gr. 2

As highlighted in our product technical data, our jam nuts meet the following rigorous requirements:

• Dimensional Accuracy (SAE J482): We ensure the thickness and width across flats are perfectly calibrated to allow for easy installation even with limited wrench clearance.
• Material Strength (SAE J995 Grade 2): Manufactured from high-quality low-to-medium carbon steel, providing the perfect balance of ductility and strength for non-critical and general-purpose assemblies.

Key Advantages of Handan Bolt Jam Nuts

• Space-Saving Design: Ideal for compact assemblies in electronics, automotive sensors, and fluid power systems.
• Vibration Resistance: When used as a pair with a standard nut, it creates an effective friction lock that resists back-off.
• Precision Threading: Our advanced tapping technology ensures smooth thread engagement, reducing the risk of galling during high-speed assembly.

Available Surface Treatments

To ensure long-lasting performance in various environments, we offer several finishing options:

• Zinc Plated (Blue/White or Yellow): The most common finish, offering good corrosion resistance and a clean aesthetic.
• Hot Dip Galvanized (HDG): Recommended for outdoor or marine applications where extra thick zinc protection is required.
• Black Oxide: Provides a sleek look and basic corrosion resistance, often used for internal machinery parts.
• Plain/Oiled: For customers who prefer a raw finish for further processing or specific industrial uses.

Common Applications

Our Hex Jam Nuts are indispensable in numerous fields:

• Automotive: Used on tie rods and control arms for alignment adjustments.
• Industrial Machinery: Securing adjustment screws and limit switches.
• Plumbing & Fluid Power: Fastening valves and fittings where height is restricted.
• Furniture Assembly: Low-profile fastening for modern office and home furniture.
