Socket Head Cap Screws (Allen) YATO set 160 pcs — without flange, assorted sizes

Set of 160 YATO socket head cap screws (Allen) without flange, assorted sizes, designed for use where a compact head and internal hex drive are required. The assortment includes multiple lengths and diameters to cover common assembly, repair and maintenance needs in mechanical, electrical and metalworking environments. The screws are suitable for fastening components where recessed or flush mounting is preferred and where torque is applied with an Allen key or hex bit.

Advantages

The set provides a comprehensive range of hex socket cap screws in one package, reducing the need to source individual sizes. The compact head profile allows use in confined spaces and recessed fittings. Internal hex drive reduces the risk of cam-out and enables controlled torque application with standard Allen keys or hex drivers. Packaged as an assorted set, it facilitates quick selection of the correct size for repair, prototyping or production tasks.

• Mechanical assembly and machine maintenance
• Electronic enclosures and equipment fastening
• Furniture assembly where recessed heads are required
• Metalwork, brackets and panel mounting
• Prototyping and workshop toolkits

Key specifications

• Head type: cylindrical socket head (Allen)
• Flange: without flange
• Quantity: 160 pieces in assorted sizes
• Drive: internal hex (Allen) compatible with standard hex keys and bits
• Typical applications: fastening in confined or recessed areas where compact head profile is needed

How to use

Select the screw size that matches the threaded hole or nut and the required engagement length. Insert the screw and turn using an appropriate-size Allen key or hex bit, applying steady torque until the required clamping force is achieved. For assembly into tapped holes, ensure threads are clean and undamaged. When fastening into thin materials or using nuts, verify that the screw length provides sufficient thread engagement without bottoming out or protruding excessively.

Usage recommendations

Use the correct hex key size to prevent rounding of the socket drive. Apply suitable threadlocker or lubrication only where specified by the application. When working with high-strength or safety-critical assemblies, follow torque specifications and material compatibility guidelines provided by equipment manufacturers.
