Unbrako 1/2 X 1.1/2 Inch Socket Set Screws (Allen/Grub Screws) - Inch, (Pack of 10)

The Unbrako 1/2" x 1-1/2 Inch Socket Set Screws (Allen/Grub Screws) are high-quality, precision-engineered fasteners that provide reliable, secure fastening for a wide range of mechanical, industrial, and automotive applications. This 100-piece set of screws, with a 1/2" diameter and 1-1/2" length, is designed for medium-duty applications where a flush, headless screw is required. Known for their strength, durability, and versatility, these screws are ideal for use in situations where traditional bolts or screws with heads are impractical.

With a hex (Allen) drive, these screws allow for high-torque installation and provide a secure connection even in tight, confined spaces. Made from hardened steel or alloy steel, they are built to withstand heavy use and are resistant to wear, deformation, and corrosion. The set is perfect for industrial, mechanical, automotive, and home DIY applications, where space is limited, and a low-profile, non-protruding screw is necessary.

Product Features:

• Size and Length: The 1/2" diameter and 1-1/2" length make these socket set screws ideal for medium-duty applications, where a sturdy, secure fastening is needed. The 1-1/2" length offers deep thread engagement, making them suitable for use in components that are thicker or require a longer screw for secure attachment. The 1/2" diameter ensures that these screws fit into standard-threaded holes, providing a robust hold.
• Material: The Unbrako 1/2" x 1-1/2 Inch Socket Set Screws are constructed from hardened steel or alloy steel, providing exceptional strength and resistance to wear, fatigue, and deformation. These materials are ideal for industrial and mechanical applications where high tensile strength is required. Some models may also feature stainless steel construction, offering additional corrosion resistance for use in environments exposed to moisture, chemicals, or corrosive elements.
• Socket (Allen) Drive: These screws feature an internal hex (Allen) drive, which allows for installation using an Allen wrench or hex key. This type of drive is highly effective for high-torque applications, ensuring the screw can be tightened securely without the risk of slippage or stripping. The Allen drive also allows for better torque control and is less likely to be damaged when compared to traditional screw heads.
• Headless (Grub) Design: These screws are headless, meaning that the screw has no external head protruding from the surface. This design provides a smooth, flush finish, making these screws ideal for applications where traditional screws with heads would be obstructive or where space is limited. The low-profile design ensures the screw won’t interfere with other components, making it perfect for tight, confined spaces.
• Thread Type: These screws feature coarse threads, which are ideal for securing parts in applications where a strong, reliable connection is needed. Coarse threads are easier to install than fine threads and are also more resistant to loosening due to vibration or mechanical movement. This makes them an excellent choice for use in machinery, automotive, and industrial applications where components are subject to dynamic forces or vibrations.
• Pack Size: The 100-piece pack provides excellent value for large-scale projects, maintenance, or industrial applications. Whether you're working on machinery, performing repairs, or simply need a bulk supply of screws for ongoing work, this pack offers the convenience and cost-effectiveness of buying in bulk.
• Corrosion Resistance: Depending on the variant, these socket set screws may come with a protective finish, such as black oxide, zinc plating, or plain steel. These finishes help protect the screws from rust, corrosion, and wear, ensuring long-lasting performance even in challenging environments. The protective coatings also help reduce friction during installation and contribute to the overall longevity of the screw.

Applications:

The Unbrako 1/2" x 1-1/2 Inch Socket Set Screws are used in a variety of mechanical, industrial, and automotive applications where a low-profile, secure fastener is required. Some common uses include:

• Mechanical Equipment: Socket set screws are commonly used to secure rotating components, such as gears, pulleys, and flywheels, onto shafts. The long length and deep thread engagement allow for a solid, stable hold on parts that are subject to high torque or rotational forces.
• Automotive Applications: These screws are ideal for use in automotive applications where space is limited, and a headless fastener is needed to secure parts like gears, pulleys, and bearings to shafts. The flush design ensures that the screw won't interfere with surrounding components, while the strong material ensures that it can withstand the demands of automotive systems.
• Industrial Machinery: The Unbrako 1/2" x 1-1/2 Inch Socket Set Screws are widely used in industrial machinery to secure parts like shafts, bearings, and gears. The coarse threads provide a strong, reliable hold in materials that are subject to dynamic forces, vibrations, or heavy loads.
• Electrical and Electronic Components: In electrical and electronic applications, these screws are used to secure components like terminals, fixtures, and connectors where a headless screw is necessary. The small, low-profile design ensures that the screw does not protrude and cause interference with other components.
• DIY Projects and Home Repairs: Whether you're assembling custom equipment, building mechanical systems, or repairing machinery, these screws are a versatile option for anyone needing a reliable fastener for their projects. The headless design is particularly useful in tight or confined spaces where a traditional screw or bolt might not fit.

Advantages:

• Durability and Strength: Constructed from hardened steel or alloy steel, these screws are designed to withstand heavy-duty use in high-stress environments, ensuring they remain strong and reliable over time.
• Low-Profile Design: The headless (grub) design allows for a flush fit, preventing the screw from protruding and interfering with other components. This makes the screws ideal for applications with limited space or where a smooth surface is necessary.
• High-Torque Performance: The Allen drive ensures that the screw can be securely tightened, even under high torque, reducing the risk of stripping the drive or damaging the screw.
• Corrosion Resistance: The screws come with protective coatings, such as black oxide or zinc plating, which provide resistance against corrosion and wear, making them suitable for outdoor or industrial applications.
• Bulk Value: The 100-piece pack offers excellent value for bulk purchasing, making it an ideal choice for industrial, mechanical, or automotive applications where large quantities of fasteners are needed.
