When it comes to screw sets, VEVOR offers a wide range of fastener types, assortments, and materials. Our collection of screw sets is built to deliver reliable fastener performance across every assembly, repair, and installation application. There are different types of nut and bolt sets for general use in the workshop, including nut bolt assortment sets, assorted nuts and bolts kits, and hex screw sets for socket head and set screw applications. Made to exact measurements, material requirements, and thread form standards for each set.
Are you looking for the right nut, bolt, or screw assortment to improve efficiency in workshop repairs or specialized installation projects? VEVOR screw sets eliminate the frustration and lost productivity that come with insufficient fastener inventory. Getting the wrong screw set can delay projects due to missing fastener sizes or failed assemblies. VEVOR screw sets are a strong choice for many workshop, trade, or professional assembly jobs. That’s because they come with the right types of fasteners, grades of materials, and ranges of sizes.
When picking screw sets for a specific job or fastener inventory need, two key factors are the set arrangement and the type of fastener. The set configuration is what determines the fastener assortment's size range, quantity distribution, and storage format.
Assorted nuts and bolts sets, also called nut bolt assortment sets, are screw sets that cover the most common fastener types. They come with bolts, nuts, and washers in a variety of metric or imperial sizes, organized in a single set. If you need a specific fastener size for a repair or assembly job, a fully stocked assortment set will have what you need right away. It saves you time by letting you skip the hardware store and finish the job.
Organize your nuts and bolts in storage cases with dividers and labeled compartments. That way, you can quickly find the right size by label without having to sort through a bunch of different loose fasteners. An assortment of nuts and bolts is useful to the extent that it covers a range of applications. For example, a set with sizes ranging from M3 to M12 is suitable for fixing electronics, bikes, and light machinery.
On the other hand, screw sets ranging from M6 to M20 are better suited for heavier structural and automotive assembly work. VEVOR offers assorted nuts and bolt sets and nut-bolt assortment sets in both metric and imperial sizes. The sets come in storage cases that keep the assortment organized even after years of use in the workshop.
Hex screw sets include the socket head cap screw format, which is a cylinder-shaped bolt with a hexagonal socket drive recess. It can accept an Allen key or a hex bit for driving. Socket head cap screws are the standard fastener choice for machinery covers, jig and fixture assembly, and mounting mechanical components. They have a high clamping force, a small head profile that fits counterbored hole installation, and precise torque application through the socket drive interface.
Set screws (grub screws) are headless fasteners with a socket-drive recess on one end and a cup, cone, flat, or dog point contact geometry on the other. They keep collars, pulleys, sprockets, and hubs attached to shafts by applying radial clamping force at the shaft surface through the tightened set screw's point contact. Screw sets come in standard metric and imperial sizes used in mechanical engineering. They also come in cup point, flat point, and cone point configurations to meet the needs of different locking applications.
Cup point set screws are used for permanent or semi-permanent shaft locking. Flat point set screw sets are used for adjustment applications where the set screw is frequently loosened and tightened. Cone point set screws are used for the highest-force shaft-locking requirement when permanent indentation of the shaft surface is acceptable.
Bolt and nut assortment kits and assorted nuts-and-bolts kits help assemblers, installers, and tradespeople choose the right fasteners for the job. They do not need the widest range of fasteners that a complete workshop set offers. Instead, they need a targeted fastener range for a certain type of project or daily work. It is better to have a bolt-and-nut assortment kit for a specific trade application. That is because it includes the fastener sizes, thread pitches, and head styles most common in that trade's daily work.
Different nuts-and-bolts kits are available in project-specific configurations. That way, DIYers and makers can buy only the fasteners they need for a given project. Bolt and nut assortment kits come in both metric and imperial sizes, with the right mix of size range, thread pitch, and head style. The kits come in portable cases that make them easy to take to the job site without losing track of the fasteners.
It is important to choose the right set configuration and fastener type for the workshop inventory or project application. The material specification and total assortment size will determine how well the screw set resists corrosion.
It is important to note that a single general-purpose material grade cannot effectively meet all application environments and structural load requirements. As a result, stainless steel (usually grade 304 or 316) in screw sets is naturally corrosion-resistant. It makes stainless steel the best material for fasteners in outdoor settings. Grade 304 stainless steel is good for most outdoor residential and light commercial uses.
However, grade 316 stainless steel with molybdenum added is better at resisting chloride-induced pitting corrosion. This makes it the right choice for fasteners in environments where salt and chlorine would cause grade 304 to pit and corrode within months.
Zinc-plated or hot-dip galvanized carbon steel fasteners offer adequate corrosion protection for interior and sheltered fastener applications. The practical corrosion-resistance service life of the plated carbon steel fastener depends on the integrity of the coating at the thread roots.
Total piece count is the most common way to describe an assortment's size, but piece count alone does not fully describe how useful the assortment is. Assortments that divide quantities evenly across all sizes have less long-term practical value than those that are adjusted proportionally based on their frequency of use in the target application. That is because assortments that divide quantities proportionally to use frequency in the target application are more useful in the long term.
If the assortment set's case or tray system is well organized, you can quickly find and use the right size. Having labeled compartments that make each size easy to find makes the assortment set useful for everyday workshop and trade use. There are different types of screw sets, with different numbers of pieces. These sets come in a range of sizes and quantities to meet the needs of most workshop and trade fastener applications.
VEVOR has all the setups, fastener types, material grades, and assortment sizes needed for a complete and reliable fastener inventory. There are different types of screw sets, including assorted nuts and bolts kits, bolt-and-nut assortment kits, hex screw sets, and set screws. All of these are made to exact measurements and from materials that ensure proper thread engagement, load performance, and corrosion resistance. Find the right type of fastener, material, and assortment size for your workshop stocking and project assembly needs by looking through all of our screw sets.
A set screw is a headless screw with a socket-drive recess on one end and a point-contact geometry on the other. When tightened, the point contact exerts radial clamping force on mechanical parts, locking them to the shafts. A standard hex bolt has a head that protrudes and a hexagonal wrench-flat shape. It also has a threaded shank that goes through holes in the joined parts and clamps them together with a matching nut.
You should use a stainless steel screw set when you want to use fasteners outdoors or where corrosion would quickly destroy the zinc coating on carbon steel fasteners. Zinc plating is good at protecting against corrosion indoors and in protected outdoor areas. Stainless steel fasteners are also the best choice for situations where replacing corroded fasteners after installation is not possible.
When choosing an assortment size, consider the case space available and the number of fasteners needed. For a home workshop that does general repairs and do-it-yourself assembly, a medium-sized assortment of 300 to 500 pieces in 15 to 25 different sizes is ideal.
