Screw & Bolt Kits

A screw and bolt kit provides a convenient and organised solution for a wide range of fastening needs. These kits contain a variety of screws, bolts, and sometimes complementary nuts and washers, pre-sorted by size and type.

At RS Australia, you’ll find a diverse selection of these nuts and bolts sets, with materials ranging from durable brass and galvanised steel to robust stainless steel bolt options, as well as non-conductive nylon. You can also choose from an assortment of thread sizes, such as M4, 4 mm, 6 mm, and others, making them ideal for everything from small household repairs to larger industrial projects.

Different Types of Screw and Bolt Sets

Barrels, cap nuts, cages, couplings, crushed, cross dowels, inserts, internal wrenching, lugs, panels, plates, flanges, hex nuts, split nuts, plate nuts, weld nuts, stakes, self-aligning nuts, swage nuts, and carriage bolts are examples of common kinds of screws and bolts. Additionally, they can be classified by their tensile strength, often into classes 5 to 10:

• Class 5: Screw and bolt kits in this class are made from low-carbon steel and are suitable for general-purpose applications where high strength is not a primary concern, such as assembling furniture or light fixtures.
• Class 8: These fasteners are made from medium-carbon steel, which has a higher tensile strength than class 5 fasteners. They are suitable for a wide range of industrial applications, including heavy machinery, automotive components, and structural steel connections.
• Class 10: These fasteners are made from high-carbon steel and are suitable for heavy-duty applications that require maximum strength and durability, such as in the construction of bridges, skyscrapers, and other large-scale structures.

Head Shape & Drive Types

The head shape and drive type determine how the screw or bolt is installed and the finished appearance. Common head shapes include button, countersunk, flat, hex, oval, and pan.

On the other hand, the drive type refers to the recess or feature on the head that accepts the tool for tightening or loosening. A screw kit will often contain a variety of these to suit different needs, and the common drive types include:

• Hex Socket: A hexagonal recess for an Allen key.
• Phillips: A cross-shaped recess.
• Pozidriv: A modified Phillips with extra radial lines for better grip.
• Slotted: A single linear slot.
• Torx: A star-shaped recess.

How to Choose the Right Screw, Bolt, and Nut Sets

When selecting a screw or bolt kit, it is crucial to consider several factors to ensure you choose the best product for your application. To simplify your work and ensure a secure and lasting connection, consider the following:

• Property Class and Strength: Fasteners are graded by strength ratings, such as ISO property classes. An ISO property class 10 nut, for instance, is designed to match the proof strength of a class 10.9 bolt without stripping. Similarly, an SAE class 5 nut can support the proof load of an SAE level 5 bolt. This system ensures that all components in a bolted connection are properly matched for strength.
• Thread Pitch: Thread pitch is also a critical consideration. Make sure that the bolt and nut have the same thread pitch to ensure a proper fit.
• Material and Finish: The material of the fastener, such as stainless steel, is important for resisting corrosion and environmental damage. The finish, like galvanisation, also adds a layer of protection and durability.
• Types of Fasteners: A good nut and bolt kit contains a variety of fasteners, including different head shapes (e.g., hex, button, countersunk) and drive types (e.g., Phillips, hex socket, Torx), to suit various applications and tools.

Industrial Applications

While nuts and bolts sets are commonly used for residential tasks, they are also essential in a wide variety of industrial applications where strength, durability, and a secure connection are paramount.

Woodworking and Construction

In woodworking and construction, a set of assorted nuts and bolts is vital for tasks that require robust fastening. Carriage bolts, for example, provide tight fittings in wood, and their secure, domed head prevents them from turning. The use of zinc, steel, or bronze materials also ensures these fasteners can handle the weight of doors, frames, and other structural components.

Marine and Coastal Environments

Screw, bolt, and nut kits made from materials such as hot-dipped galvanised steel and stainless steel are widely used in outdoor and seaside settings. These materials offer high durability and can withstand exposure to harsh weather and saltwater without rusting, thereby ensuring the integrity of structures and machinery in these environments.

Aesthetic and Functional Applications

In addition to their strength, some nut and bolt sets are chosen for their aesthetic properties even in industrial settings. Grade 2 chrome, for instance, offers a shiny, mirror-like finish that is ideal for applications where a clean, polished appearance is desired.
