HONBAY 100PCS M3x5 Black Zinc Round Head PC Mounting Computer Screws Computer Ca vs uxcell uxcellComputer PC Case 3.5-inch HDD 6#-32 Flat Phillips Head Hard Drive S

Overview and Packaging

The HONBAY 100PCS M3x5 and the uxcell uxcellComputer PC Case 3.5-inch HDD screws both come in packs of approximately 100 pieces, making them suitable for bulk use in computer assembly or maintenance. Specifically, HONBAY offers 100 screws per package, while uxcell provides around 100 screws with a possible 2% variance, ensuring ample quantity for various projects.

HONBAY’s screws come in black zinc color, made from carbon steel C1010, which suggests a sturdy and corrosion-resistant finish. In contrast, uxcell’s screws have a silver tone with a nickel plating, which also offers some corrosion resistance but with a different aesthetic. Both packages cater to users needing multiple screws for mounting purposes, but the material and coating differences might influence durability and appearance depending on the user’s preference.

Dimensions and Specifications

When comparing sizing, the HONBAY screws measure M3x5 with a total length of 7mm, including a 5mm thread length, head width of 7mm, and head thickness of 2mm. The thread pitch is 0.5mm, indicating metric threading. The head shape is a round head with a pad, designed to fit a #2 Phillips driver.

The uxcell screws have a thread size of 6# (3.5mm diameter) and a total length of 5mm (0.2 inches). Their threading is UNC with a thread count of 32, which is typical for imperial screw standards. These screws feature a flat Phillips head designed for 3.5-inch HDD mounting, matching their intended application.

In short, HONBAY screws are metric with a slightly longer overall length (7mm vs. 5mm) and a round head, while uxcell screws use imperial sizing with a flat head and are shorter in total length. These differences will influence which screws fit specific mounting points and tools.

Material and Durability

HONBAY screws are made from carbon steel C1010, a material known for strength and durability in hardware applications. The black zinc coating provides corrosion resistance and an aesthetic black finish that may reduce glare or match darker components.

Uxcell screws are metal with a nickel plating, which also protects against rust and corrosion but results in a silver-toned finish. Nickel plating tends to be smooth and shiny, potentially offering a different tactile feel and resistance level compared to zinc.

Both materials are suitable for computer hardware mounting, but the choice between carbon steel with black zinc and nickel-plated metal may come down to personal preference for colour, finish, and specific environmental resistance needs.

Head Type and Drive Compatibility

The HONBAY screws feature a round head with a pad and are compatible with a #2 Phillips driver. This head shape can distribute pressure over a wider area, which might be preferable for mounting cases where surface deformation is a concern.

On the other hand, the uxcell screws have a flat Phillips head designed for hard drive mounting, particularly 3.5-inch HDDs. They use a drive type of Phillips as well but in a flat head form, which generally sits flush with the mounting surface, providing a cleaner look and potentially less obstruction.

Depending on whether a round or flat head is needed for the specific computer component, users might prefer one over the other. The HONBAY’s round head is broader and slightly thicker at 2mm, whereas uxcell’s flat head is designed for flush fitting in tight spaces.

Intended Use and Compatibility

The uxcell screws are explicitly designed for 3.5-inch hard drive mounting in PC cases, with specifications such as thread size 6#-32 and compatibility for HDDs, power supplies, and expansion cards. Their shoulder design helps with shockproof mounting, which is beneficial for sensitive hard drives.

HONBAY’s screws, while also marketed for PC mounting applications, have a more general-purpose description for computer case mounting, without specific mention of HDD compatibility. Their M3x5 size and round head make them versatile for various computer hardware requiring metric screws.

Therefore, if your primary need is mounting 3.5-inch hard drives or components that require 6#-32 screws, uxcell offers a targeted solution. For broader PC mounting needs, especially where metric screws are preferred, HONBAY’s offering might be more appropriate.

Weight and Physical Feel

While the HONBAY product description does not specify weight, the uxcell screws have a total pack weight of 28 grams for approximately 100 pieces. This suggests that each uxcell screw is lightweight, which is typical for small computer screws.

Given that HONBAY screws are slightly longer and made from carbon steel, they might be marginally heavier per piece, although exact weights are not provided. The weight difference is likely minimal but could affect handling, especially when dealing with many screws during assembly.

Users concerned about screw weight for delicate applications might consider the uxcell screws, which have a known light weight, while those valuing material strength might prefer HONBAY’s carbon steel screws despite possible additional weight.

Price Comparison

The uxcell screws are priced at C$9.79 for a pack of approximately 100 screws, making them the more affordable option between the two. HONBAY’s pack costs C$20.22 for 100 screws, which is more than double the price of uxcell’s offering.

Given the price difference, uxcell provides a budget-friendly option for those needing a large quantity of hard drive mounting screws. HONBAY’s higher price might be justified by the carbon steel material, black zinc finish, and metric specifications, but for cost-conscious buyers, uxcell offers significant savings.

Ultimately, the price gap may influence purchasing decisions, especially if quantity and budget are key factors.

Which should you buy?

Choosing between HONBAY 100PCS M3x5 Black Zinc Round Head and uxcell uxcellComputer PC Case 3.5-inch HDD screws depends on your specific needs for size, head type, and budget. If you require metric M3x5 screws with a round head and black zinc finish for general computer case mounting, HONBAY offers a reliable but pricier option at C$20.22 per 100 screws. Their carbon steel material may provide added strength and corrosion resistance for demanding applications.

Conversely, if you need screws specifically for 3.5-inch hard drive mounting with 6#-32 UNC threading, a flat Phillips head, and a silver nickel-plated finish, the uxcell screws at C$9.79 per 100 are a cost-effective and appropriate choice. Their design includes shockproof mounting features and fits standard PC HDD needs.

For general purpose PC mounting where metric screws are preferred, HONBAY is ideal despite the higher cost. For drive-specific mounting and budget-conscious buyers, uxcell’s screws are the practical pick.
