Unbrako 5/16 X 1.1/2 Inch Socket Set Screws (Allen/Grub Screws) - Inch, (Pack of 10)

The Unbrako 5/16" x 1.1/2 Inch Socket Set Screws (also known as Allen or Grub Screws) are high-performance, precision-engineered fasteners designed for a wide variety of industrial, mechanical, automotive, and DIY applications. Manufactured from hardened steel or alloy steel, these screws are built to withstand mechanical stress, vibration, and wear, ensuring long-lasting, reliable performance in demanding environments.

Key Features:

• Size and Dimensions: These screws measure 5/16" in diameter and 1.1/2 inches in length, making them ideal for medium-duty applications where a secure, compact fit is required. The 1.1/2-inch length provides optimal thread engagement, while the 5/16-inch diameter offers strong tensile strength for dependable fastening.
• Material: Made from hardened steel or alloy steel, the screws are engineered to handle high stresses and resist wear over time. This material choice ensures that the screws maintain their strength and integrity, even under heavy-duty conditions, offering excellent performance and durability.
• Coarse Threads: These screws feature coarse threads, which are designed to provide a secure grip in a variety of materials, including metals, plastics, and wood. The coarse thread design allows for quick engagement and stronger holding power, making them ideal for applications that require a reliable and secure fastener.
• Headless Design (Grub Screw): The screws are headless, meaning they are designed to sit flush with the surface once installed. This low-profile design is ideal for use in confined spaces where a protruding screw head might interfere with surrounding components. The flush fit ensures a smooth, clean finish, which is important in applications where aesthetics or space constraints are key considerations.
• Hex (Allen) Drive: These screws come with a hexagonal (Allen) drive for installation, which provides a secure and precise fit. The hex drive allows for greater torque application with an Allen wrench or hex key, minimizing the chances of slippage or stripping that can occur with traditional slotted or Phillips head screws. The design is particularly well-suited for applications in tight spaces, where conventional screwdrivers may not be effective.
• Bulk Pack of 200: These screws come in a 200-piece pack, offering excellent value for large-scale projects or routine maintenance. Whether you're working on machinery, equipment repairs, automotive systems, or large construction projects, this bulk pack ensures you have a sufficient supply of screws, reducing the need for frequent reordering.
• Corrosion-Resistant Coating: Depending on the specific model, the screws may be coated with black oxide or zinc plating, which helps improve their resistance to rust and corrosion. This coating adds durability and makes them suitable for use in environments exposed to moisture or chemicals, ensuring they perform well in both indoor and outdoor settings.

Applications:

The Unbrako 5/16" x 1.1/2 Inch Socket Set Screws are versatile fasteners that can be used in a wide range of applications across various industries. Some of the most common uses include:

• Mechanical Equipment: These screws are ideal for securing components in machinery, motors, gearboxes, pumps, conveyors, and other mechanical systems. Their headless design allows them to fit into tight spaces where traditional screws may be too bulky, while the coarse threads ensure a strong and reliable grip, even under high-stress conditions.
• Automotive Applications: In automotive repairs and vehicle assembly, these screws are commonly used to secure parts like brakes, suspension systems, engine components, and transmission assemblies. The flush fit design makes them suitable for applications where space is limited, and the hex drive allows for easier tightening and installation.
• Industrial Machinery and Equipment: These screws are frequently used in industrial equipment like cranes, robotic arms, industrial machinery, and manufacturing systems. Their hardened steel construction ensures they can handle the heavy demands of industrial applications, while their low-profile design prevents interference with other components in tight spaces.
• Electrical Assemblies: In electrical systems, these screws are used for securing components in electrical enclosures, circuit boards, and electrical connectors. The flush head design is ideal for use in electrical enclosures where protruding screws could cause damage or interfere with other parts, and the coarse threads ensure a secure and reliable hold in softer materials.
• DIY and Home Improvement: These screws are also great for DIY projects, appliance repairs, or home improvement tasks. Whether you're working with wood, plastic, or metal, the versatility of the 5/16" x 1.1/2" screws makes them an excellent choice for a wide variety of materials and applications.

Benefits:

• High Strength and Durability: Constructed from hardened steel or alloy steel, these screws are strong, durable, and designed to withstand harsh conditions. Whether used in machinery, vehicles, or electrical systems, these screws are built to last and resist wear over time.
• Flush Fit for Tight Spaces: The headless design allows the screws to sit flush with the surface, making them perfect for use in confined spaces or where a smooth, low-profile finish is necessary. This feature is particularly beneficial in industrial, automotive, and electrical applications.
• Reliable Grip with Coarse Threads: The coarse threads provide superior grip and holding power, ensuring the screws stay securely in place, even under vibration or stress. The coarse threads are also easier to install and remove, reducing the risk of stripping.
• Easy to Install with Allen Drive: The hex (Allen) drive ensures precise installation and reduces the risk of stripping, allowing for better torque control and making it easier to work in tight spaces where traditional screwdrivers may not fit.
• Corrosion Protection: The optional black oxide or zinc plating coating provides additional protection against rust and corrosion, making these screws suitable for use in both indoor and outdoor environments, as well as in harsh, corrosive conditions.
• Bulk Packaging: The 200-piece pack is ideal for large projects or high-volume applications, offering significant savings and ensuring you have plenty of screws on hand for repairs, maintenance, or assembly tasks.
