How to Choose the Best Screw & Bolt Assortment Sets
Types of Fasteners
Screw and bolt assortment sets typically include a variety of common fasteners. Screws generally have threads that run along the entire shaft and are designed to be driven into materials like wood or plastic. Bolts, on the other hand, usually have unthreaded shanks and are used with nuts to fasten materials together. Common types include wood screws, machine screws, lag bolts, and carriage bolts, each suited for different applications.
Material and Durability
The material of the fasteners is crucial for their strength and resistance to corrosion. Steel is common, often coated with zinc for added protection against rust. Stainless steel offers superior corrosion resistance, making it ideal for outdoor or moist environments. Titanium is lightweight and strong but less common in general assortments. Consider the intended use of the set when evaluating materials; for heavy-duty applications, look for hardened steel.
Thread Types and Sizes
Fasteners come with different thread pitches (coarse or fine) and diameters. Coarse threads are generally used in softer materials like wood, while fine threads are better for harder materials and offer a more secure hold. Assortment sets aim to cover a range of common sizes, but it's important to check the specific dimensions included to ensure they meet your needs. Standard measurements are often in inches (e.g., #8, 1/4 inch) or metric (e.g., M4, M6).
Organization and Storage
A good assortment set comes in organized storage. This typically involves a compartmentalized plastic case that keeps each type and size of fastener separate and easily accessible. Look for cases with secure latches to prevent spills. Some higher-end sets may offer durable metal or wooden boxes. Proper organization is key to quickly finding the right fastener and maintaining an inventory of your supplies.
Comparison Tips
Count vs. Variety: Decide if you need a large quantity of a few common types or a wider variety of specialized fasteners.
Application Focus: Consider the types of projects you undertake most often. Are you building furniture, performing repairs, or working on electronics?
Included Hardware: Some sets may include complementary hardware like washers and nuts, which can add significant value.
Case Quality: A sturdy, well-designed case can make a big difference in the long-term usability of the set.
Frequently Asked Questions
What is the difference between a screw and a bolt?
Screws are typically designed to be driven into a material, creating their own threads or engaging with pre-tapped holes. Bolts are usually used with a nut and washer to clamp two or more objects together.
What does 'coarse thread' vs. 'fine thread' mean?
Coarse threads have fewer threads per inch and are generally used in softer materials like wood for faster driving. Fine threads have more threads per inch, offering a stronger hold in harder materials and better resistance to loosening from vibration.
Why are some fasteners coated?
Coatings like zinc or galvanization are applied to fasteners to protect them from rust and corrosion. This is especially important for fasteners used in outdoor or high-moisture environments.
Are metric and standard (SAE) sizes interchangeable?
No, metric and standard (SAE - Society of Automotive Engineers) fasteners are not interchangeable. They use different measurement systems and thread pitches, so you must use the correct size nut or hole for each type.
What is a lag bolt used for?
A lag bolt is a heavy-duty wood screw with a hex head, designed for fastening heavy objects to wood. They are commonly used in structural applications like deck building or framing.
How should I store my fastener assortment set?
Store your set in its original case or a similar organized container to keep different types and sizes separated. Keep the case in a dry environment to prevent corrosion.
