Unbrako 5/16 X 1.1/4 Inch Socket Set Screws (Allen/Grub Screws) - Inch, (Pack of 10)

The Unbrako 5/16" x 1.1/4 Inch Socket Set Screws (Allen/Grub Screws), available in a 200-piece pack, are precision-engineered fasteners designed for a wide range of industrial, mechanical, automotive, and electrical applications. These high-performance, headless screws are made from hardened steel or alloy steel, ensuring excellent strength, durability, and wear resistance even in demanding environments. Their flush-fit, headless design allows for secure fastening in tight or confined spaces where traditional screws would not be practical.

Key Features:

• Size and Dimensions: These screws measure 5/16" in diameter and 1.1/4 inches in length, making them suitable for medium-duty applications requiring secure, reliable fastening. The 1.1/4-inch length provides optimal thread engagement, ensuring strong grip in a variety of materials. The 5/16-inch diameter offers strength and stability for a wide range of industrial and mechanical uses.
• Material: Crafted from hardened steel or alloy steel, these screws are built to withstand heavy-duty stresses and resist wear over time. This material ensures that the screws maintain their integrity even under high pressure, frequent use, or exposure to harsh conditions.
• Coarse Threads: Featuring coarse threads, these screws are ideal for quick engagement and secure fastening in materials such as metal, plastic, and wood. The coarse threading provides increased holding power and is particularly well-suited for applications where a strong grip is needed in a variety of environments.
• Headless Design: These screws are headless, meaning they do not protrude above the surface after installation. This makes them perfect for use in applications where a low-profile, flush fit is essential, preventing interference with surrounding components. The flush-fit design ensures smooth surfaces and helps avoid damage to machinery or other equipment.
• Hex (Allen) Drive: The hex drive allows for secure and precise installation using an Allen wrench or hex key, which reduces the risk of stripping the screw or damaging the material during installation. The hexagonal shape provides excellent torque application and a firm grip for efficient tightening and loosening.
• Corrosion-Resistant Finish: Depending on the specific model, the screws may feature a zinc-plated or black oxide finish for improved corrosion resistance. This finish protects the screws from rust and degradation, making them suitable for use in environments exposed to moisture, chemicals, or outdoor elements.
• Bulk Pack of 200 Pieces: These screws are sold in a 200-piece pack, providing excellent value for businesses, maintenance professionals, or DIY enthusiasts. The bulk pack ensures that you have an ample supply of screws for large-scale projects, repairs, or routine maintenance, reducing the need for frequent reordering.

Applications:

The Unbrako 5/16" x 1.1/4 Inch Socket Set Screws are versatile fasteners ideal for a range of industries and applications, including:

• Mechanical and Industrial Equipment: These screws are commonly used to secure components in motors, gearboxes, pumps, and conveyor systems. Their headless design is particularly useful for tight spaces where protruding screw heads would be impractical or could interfere with machinery operation.
• Automotive Repairs: In the automotive industry, these screws are often used to secure components such as brake systems, suspension parts, engine components, and electrical systems. The low-profile, flush-fit design ensures they won’t get in the way of other moving parts or cause any interference.
• Electrical Systems: These screws are also commonly used in electrical enclosures, circuit boards, and electrical connectors, where space is limited and a smooth, flush surface is required. The corrosion-resistant coating ensures the screws hold up well in both indoor and outdoor electrical installations.
• DIY and Home Projects: Whether you’re working on woodworking, home repairs, or appliance maintenance, these screws are perfect for wood, metal, and plastic applications. The flush fit and coarse threads make them ideal for securing parts without causing damage or protruding.
• Aerospace and Defense: In specialized industries like aerospace and defense, these screws provide secure fastening in critical applications where strength, reliability, and a low profile are required. Their resistance to corrosion and high performance under stress make them well-suited for demanding environments.

Benefits:

• Strong and Durable: The hardened steel or alloy steel construction ensures long-lasting strength and reliability, even in high-stress or harsh environments. These screws are designed to withstand repeated use and heavy-duty applications without losing their grip or integrity.
• Low-Profile, Flush Fit: The headless design ensures that the screw sits flush with the surface, making it ideal for applications where space is tight or where protruding screw heads would interfere with surrounding components. This makes the screws suitable for machinery, vehicles, and electrical enclosures.
• Corrosion Resistance: The zinc-plated or black oxide finish offers enhanced protection against rust and corrosion, ensuring the screws remain effective and reliable even in environments exposed to moisture, chemicals, or outdoor conditions.
• Easy Installation: The hex (Allen) drive provides a secure, high-torque fastening solution that minimizes the risk of stripping. The use of an Allen wrench or hex key allows for precise control during installation, making it easier to install or remove the screws without damaging the surrounding material.
• Cost-Effective: Sold in a 200-piece bulk pack, these screws provide excellent value for professionals, businesses, and DIY enthusiasts. The bulk packaging ensures that you have a sufficient supply of screws for large projects, repairs, or ongoing maintenance without having to frequently reorder.
• Versatile and Multi-Purpose: These screws are designed for a wide range of applications, from industrial machinery and automotive systems to electrical installations and home improvement projects. Their durability, versatility, and flush-fit design make them a reliable choice for a wide variety of fastening needs.
