Laptop repair screw set with 1.4mm diameter black-plated machine screws for PC maintenance

This set provides a practical supply of small machine screws specifically sized for internal computer and laptop assembly. Designed for repair technicians and hobbyists, it offers a bulk quantity of fasteners to replace lost or damaged screws during disassembly. The screws feature a countersunk head with a cross-drive groove, intended for manual installation with a standard screwdriver. Available in three different box sizes, it allows users to select a quantity that matches their anticipated repair workload, from occasional fixes to more frequent servicing tasks.

Features and Construction

The set contains standardised machine screws designed for general fastening applications within electronic devices. Their specifications are chosen to be compatible with the screw threads commonly found in laptop chassis and internal component mounts.

Material and Build

The screws are made from carbon steel grade 4.8, a material offering standard mechanical properties for this type of fastener. The surface has been treated with a black plating, which provides a consistent finish and offers a basic level of corrosion resistance. This construction is typical for commercially available machine screws used in non-critical electronic assembly where high tensile strength is not the primary requirement.

Size and Practical Fit

Each screw has a diameter of 1.4mm and a length of 16mm, a size profile frequently used for securing smaller brackets, daughterboards, and covers inside laptops and compact electronics. The countersunk head design allows the screw to sit flush with or below the surface of the material it is fastening, which is important in tight internal spaces. The cross-drive (Phillips) groove is specified for hand-twist action, making it suitable for controlled manual tightening without the need for power tools.

Uses and Placement

These screws are intended for fastening tasks where a small, precise fastener is needed. Their primary application is in the reassembly of portable computers and other electronic devices after maintenance or upgrade work.

Event or Professional Use

For IT support technicians, repair shop workers, or enthusiasts who perform multiple laptop repairs, the larger box quantities (650 or 720 pieces) provide a convenient stock of consumable parts. Having a ready supply of the correct screw size reduces downtime spent searching for replacements and ensures a complete, professional reassembly. The standard thread and common dimensions mean these screws can be used across many different laptop models and brands that utilise this size.

Everyday Home Use

For the individual user performing a one-off upgrade, such as adding memory or replacing a hard drive, the smaller 450-piece box offers more than enough screws for the task while leaving spare parts for future needs. The hand-twist mode of action makes them safe and easy to use without specialist knowledge or equipment, supporting DIY computer maintenance.

Benefits and Buying Value

The value of this product lies in providing a specific, ready-to-use component that addresses a common need in electronics repair. It eliminates the frustration of mismatched or missing screws.

Reuse and Low Maintenance

The screws are designed as replacement parts, allowing users to restore a device to its original assembled state. Their simple metal construction requires no specific maintenance or care. The black plating helps maintain a consistent appearance with original equipment manufacturer (OEM) screws commonly found in electronics. The product's A-grade classification indicates it meets standard quality criteria for such components.

Why Choose This Product

This set is a straightforward solution for anyone who needs a reliable supply of correctly sized laptop screws. The choice between three box sizes (450, 650, 720 pieces) lets users match their purchase to their expected usage, avoiding waste or shortage. The specifications—1.4mm diameter, 16mm length, carbon steel grade 4.8, black plating—are clearly stated, ensuring you receive the exact type of fastener required for the job.
