When looking at the head of a bolt, there are six details that can be told by them: the type of fastener (or drive type), the grade (or classification) of the fastener, the manufacturer, the material type, the plating or coating and whether it is an Imperial fastener or a Metric fastener.
These details can be broken down into various groups called Grades or Classes that classify them according to their property ranks, quality, degree and other various facets. According to Imperial (SAE) and Metric specifications, as the grade and class of the fasteners increase, so do that of the bolt’s tensile strength.
How a Recoil Wire Thread Insert Works: Recoil wire thread inserts are rolled from high quality stainless steel wire with a diamond shaped cross section, wound to the shape of a spring thread. Once the insert is installed into a tapped hole, it provides a permanent and wear resistant thread in the parent material that is stronger than the original thread.
Recoil inserts are greater in diameter than the corresponding tapped hole and compress as they are installed. This allows maximum surface contact area with the tapped thread, safely and permanently anchoring the inserts into place.
The kind of hole to be tapped has much to do with the style of tap that’s best suited. Some holes go all the way through. Others, while not through holes, still are relatively deep. Some are quite shallow, little deeper than diameter. Each of these three kinds of holes through, deep-bottoming blind, and shallow bottoming, has a tap or group of taps best suited to requirements.
What is the problem?
Workers can sustain eye injuries when exposed to airborne fragments from work processes such as cutting, drilling or grinding metal, timber or other materials.
What are the risks?
Eye injuries include lacerations and penetration injuries, and can result in scarring, loss of clear vision, and partial or complete blindness.
Speeds and feeds are the most important considerations to achieve the best results from cutting tools. Improper speeds and feeds often cause low production, poor quality, and damage to the tool. Speeds that are too high or feeds that are too light can lead to rapid wear and dulling of the cutter, reducing tool life.
Speed is measured in peripheral feet per minute. It is often referred to as cutting speed or surface speed. Feed is usually measured and stated in inches per minute (IPM). It takes into consideration the number of cutting teeth (or flutes), the feed per tooth (or cutting edges), and the revolutions per minute.
Drill bits are meant to be sharpened! Drill Doctor can restore worn drill bits to factory-sharp condition in under a minute.
More than a million people sharpen their dull and broken drill bits with one of the award winning Drill Doctor drill bit sharpeners.
The expense of a project is nothing compared to the cost of the tools to do the job. To get a job done right you need sharp tools and nothing does a worse job than a dull drill bit.
Industrial grade lubricant that you can use in the house, garage and shop. In laboratory tests, ProTecta with its extreme pressure additives withstands 5 times the lubricating pressure of the leading brands to eliminate squeaks and lubricate longer. ProTecta’s advanced formula provides a superior lubricating film that continues to provide protection when the oil dries. It adheres to metal better than other spray lubricants, and it cleans most surfaces and quickly penetrates and loosens frozen or rusted metal parts. Makes all other spray oils obsolete! Resists water and drives moisture from working surfaces. Evaporates leaving a protective, long lasting, non-sticky, dust-free film.
Push effort & ride comfort
Major design factors that affect wheel selection are:
1. Push effort on smooth floors
The amount of force required to push equipment on smooth floors such as vinyl, commercial carpet and smooth concrete.
2. Push effort on rough floors
The amount of force required to push equipment on rough floors such as bitumen or over obstacles like elevator door jams and joins between tiles and carpet.
Metal Corrosion occurs where metals are left exposed to moisture within the air. This is due to a reaction with oxygen which in turn creates rust and eventually leads to corrosion. Perform these simple steps to give your new steel the best protection and longevity from corrosion.
Step 1 – Clean It
1. Remove all rough surfaces such as sharp edges, mill scale and weld splatter by abrading, sanding or wire brushing.
2. Remove contaminants and foreign particles using a clean cloth and a suitable non-residue solvent such as Galmet® Enamel Spraying Thinner 300C.
While most of us have general cleaning equipment handy (brooms, mops, sponges etc.) it’s always nice to have a few little tips and tricks up your sleeve! Read on to discover our list of 10 handy cleaning tips!
- While sweeping, avoid getting your broom wet. It can damage the bristles and shorten the life of your broom. If you have to wash your broom dry it upside down to prevent the bristles from becoming bent or damaged.
- If your glassware come out of your dish washer a little cloudy, fix the problem by adding about one teaspoon of Epsom Salts the next time you do a cycle. Your glasses should come out sparkling!
