A Mouthful of Socket Head Cap Screws

June 10th, 2021

For ordinary people like us, tools such as wrenches, hammers, bolts, etc., are just a jargon of words we often hear. It came to my mind that we have to educate ourselves at least at some point, and so let us start with the most common tool: The Socket Head Cap Screw. It is a type of cap screw with a hexagonal recessed drive and specifically designed to test the amount of tensile (stretching) stress a material can withstand before breaking or failing and for die applications. They also are usually made from stronger alloy steel vs. other screws, but this depends on the grade and the manufacturer. They are fastened using a socket wrench and have different types of head designs which includes a cylindrical head, a button head and flat head, the latter designed to be seated into countersunk holes. Amongst the different types of screws, the Socket head cap screws are commonly utilized in the industry because of its safety, reliability and economy. They are used for machine assembly, especially for removable parts, and for applications with limited spaces since they take up less space and don’t require side room for wrenches. Another factor is that compared to ordinary screws, less socket screws can achieve the same clamping force in a joint. As fewer screws are used for a given job, fewer holes are required to be drilled, there is also considerable weight reduction. However, they also have three disadvantages. First, they have small heads. If they are to be loaded in tension, the limited bearing area under the head will prevent tightening the bolt sufficiently to take full advantage of the strength of the alloy. Second, they are manufactured with very long thread, which is the ridge wrapped around a cylinder or cone in the form of a helix. And third, the heads are case hardened and are therefore difficult to drill for safety wire.

Since there are different types of socket head cap screws nowadays, you have to choose what size and design your going to use. Because of this, you need to be careful in purchasing the items you need. You have to keep in mind that different types of screws also have different purposes. In other words, certain screws are made for certain types of machines, tools, or projects. A range of choices for special use applications are:

• High temperature
• Corrosive environments
• Maximum tensile strength critical
• Cleanliness required

There are ways to choose the right screw to use. First, know what you’re screwing into. Socket head cap screws or any screw are labeled according to their use. If you are uncertain, you may ask the hardware attendant or consult a professional. But usually, you have to consider the thickness of the material you’re joining. Secondly, keep in mind that there are types of the socket head cap screw that are made from stainless steel, while some are not. Because of this, it is best that your hardware store so that you will be able to purchase the right type screw.

These are some of the tips on how to purchase the right type of screw. Although they are small things, it is best to follow such tips, to avoid any unnecessary hassles.

Carpentry Fun Time: Inserting Screws

January 10th, 2021

Today is a great day to help your child learn how to insert screws into wood. By the end of these quick projects they will even have a key holder to hang by your door!

Here are the supplies you’ll need for these activities: sandpaper, a starter nail, a bar of soap, a few blocks of soft wood, some narrow pieces of wood (approximately 12 inches long), an assorted variety of screws (hook, eye, straight wood, etc.) and a variety of screwdrivers. Make sure that the screws you have will be comfortable for you child to handle; in other words, no screws over three inches long unless your child can handle them!

Simple Screw Fun

Once you’ve helped your child set up the carpentry work space with their workbench and supplies, have them partially hammer a nail into a block of soft wood and then wiggle it out. You may want to show them how to do this. Then, have them rub the end of a screw on the bar of soap and then screw it with a screwdriver into the nail hole. Let your child practice screwing and unscrewing the screw. Try different types of screws. Show them that once they have a starter hole, they can even screw in an eye screw or a hook screw by twisting it into the wood – they won’t even need a screwdriver!

Which Screwdriver?

Prepare a block by screwing in various types and sizes of screws into the wood. Make sure you include a few Phillips head screws in your assortment. Set out a variety of screwdrivers and let your child experiment with finding out which screwdriver works best on each screw. Have them explain to you why this screwdriver works best on this screw and that one works best on that screw, etc.

Key Holders

Now we’re ready for our project! Have your child sand the narrow pieces of wood until they are nice and smooth. Next, have them screw in four hook screws across the front of their wood piece. On the top of the wood piece, have them screw in two eye hooks for hanging, one on each end of the wood. If they’re feeling creative, have them decorate their key holders with stickers, paint or decals. Tie some string through the eye hooks and there you have it! One completed key holder, ready for use. Now we just have to have them clean up their workbench, put all the supplies and tools away and we’re done.

Can your child think of other things to make with the screws and wood
