Laptop Repair Screw Set: 1.4mm Black Countersunk Machine Screws in 450, 650 or 720-Piece Assortments

Assembling or repairing laptops, small electronics, and precision devices often requires specific, hard-to-find hardware. This assortment provides a practical solution: a bulk supply of standard 1.4mm diameter machine screws with a 16mm length, designed for manual installation. Available in three different box quantities, it allows hobbyists, IT technicians, and DIY enthusiasts to select the right volume for their needs, whether for a one-off repair or to stock a workshop bench. The screws feature a countersunk flat head that sits flush with surfaces, a cross-head (Phillips) drive for common tools, and a black plated finish, making them a functional and versatile choice for a range of light mechanical and electronic fastening tasks.

Features and Construction

This product is defined by its standardised specifications and functional design, tailored for electronics and small-scale assembly work where precise, readily available fasteners are essential.

Material and Build

The screws are manufactured from carbon steel graded at 4.8. This is a common grade for general-purpose machine screws, indicating a standard level of tensile strength suitable for the loads typically encountered in laptop casings, electronic device frames, and other non-structural applications. The surface treatment is a black plating, which provides a consistent colour and offers a base level of protection against oxidation in normal indoor environments. The product is classified as A-grade, denoting a standard commercial quality suitable for its intended use.

Size and Practical Fit

The key specifications are a 1.4mm screw diameter and a 16mm length. This combination is a frequent standard in electronics manufacturing and repair, particularly for securing internal components, mounting boards, or assembling thin plastic and metal housings. The countersunk head is designed to taper into a matching recessed hole, allowing the screw head to sit flush with or below the surface, which is crucial for internal components and for maintaining a smooth exterior finish on devices.

Uses and Placement

With their specific dimensions and head type, these screws serve distinct roles in both professional and personal settings where small, standardised fasteners are needed.

Event or Professional Use

For IT support technicians, electronics repair shops, or mobile phone repair services, having a reliable stock of common screw sizes is vital. This assortment, particularly the larger 650 or 720-piece boxes, provides a replenishable source for frequently used 1.4mm screws, reducing downtime spent sourcing individual pieces. The standard cross-head drive ensures compatibility with ubiquitous Phillips-head screwdrivers found in any toolkit, facilitating quick and efficient repairs on a range of consumer electronics beyond just laptops.

Everyday Home Use

For the home DIYer or hobbyist, this set is a convenient resource for repairing personal laptops, gaming consoles, remote controls, or small appliances. The availability of a 450-piece box is ideal for those who need a supply for occasional projects without significant leftover inventory. The screws are also useful for crafting, model-making, or other small creative projects that require discreet, low-profile fasteners. The manual "hand twist" mode of action means no special power tools are required, making them accessible for all skill levels.

Benefits and Buying Value

The value of this product lies in its specificity, volume options, and the practicality of having a dedicated supply of a commonly used component.

Reuse and Low Maintenance

As a hardware assortment, the primary benefit is reuse; a single box can service multiple repair jobs over time. The screws are not a consumable item in the traditional sense and, if undamaged, can be reused in other applications. Their simple carbon steel construction and plated finish require no special maintenance when stored in a dry environment. Choosing the correct box size from the outset minimises waste and ensures you have an adequate supply without excessive leftover stock.

Why Choose This Product

This product addresses a clear gap: the need for an accessible, bulk supply of a specific electronics screw size. Instead of searching for individual screws or buying incompatible assortments, this set delivers exactly what is needed for many common repairs. The three quantity options allow you to match your purchase to your anticipated usage, providing cost-effectiveness for both casual and frequent users. The combination of standard dimensions (1.4mm x 16mm), a flush-fitting countersunk head, and a common drive type makes it a directly applicable and practical solution for anyone working with small devices.
