Types of Hand Spanners available in Indian market -

Here are some of the most common types of hand spanners and their uses:

Open-Ended Spanners

Ring Spanners

: Also known as “box spanners”, ring spanners have a closed loop head that fits over the nut or bolt head. This design allows them to grip the fastener more securely than open-ended spanners, making them suitable for use in high-torque applications.

Adjustable Spanners

: Also known as “monkey spanners” or “crescent spanners”, adjustable spanners have a movable jaw that can be adjusted to fit a wide range of fastener sizes. They are incredibly versatile and can be used in place of several other spanner types.

Socket Wrenches

Top factors to consider before buying Hand Spanners –

When it comes to buying a hand spanner, there are a few important factors to consider that will ensure you get the best tool for the job. Firstly, take into account the length of the hand spanner. You want to make sure you have the right size for whatever you’re working on. The most common lengths are 6-inch, 8-inch and 10-inch. The longer the spanner, the more torque you can apply and the better access you’ll have to tight spaces.

Next, consider the profile of the hand spanner. There are two types of spanner profiles – open-end and box-end. Open-end spanners provide access to two or three sides of a nut or bolt, while box-end spanners provide access to the entire nut or bolt. Box-end spanners are great for tight spaces where you need to be able to apply more torque.

The width and thickness of the head of the hand spanner is also important. Make sure you buy the right size for the job. Too thick or wide of a head can make it difficult to access tight spaces, while too thin or narrow can cause damage to the nuts or bolts.

Finally, consider the material of the wrench. Steel is the most common material used, as it is strong and durable. There are also wrenches made from titanium and aluminium, which are lighter and easier to manoeuvre, but not as strong.

When it comes to size, the size of the hand spanner will depend on the type of work you’re doing. For larger jobs, a larger size is best, while for smaller jobs, a smaller size is better. Remember, the size of the spanner will also determine how much torque you can apply.

By considering these factors, you can make sure you buy the right hand spanner for your job.

Hazards of using hand spanners –

Hand spanners are tools used to tighten or loosen a bolt or nut. Though these tools are widely used in industrial and domestic settings, they can also be hazardous if used in the wrong way. Here are some of the dangers of using hand spanners:

1. Injury: Hand spanners are typically made of steel, which can be sharp and can cause serious injury to the skin and underlying tissues if they are not used properly. Accidental slips can also cause cuts and bruises as the edges of the spanner can sometimes be sharp.

2. Over-tightening: Over-tightening a bolt or nut with a hand spanner can cause damage to the bolt or nut, or even the surrounding material. This is especially true for softer metals such as aluminium or brass, which can easily be damaged by excessive force.

3. Stripping: Applying too much pressure with a hand spanner can strip a bolt or nut, which can weaken it and make it even more dangerous. Stripping a bolt or nut can also cause them to become stuck, making it difficult to remove them.

4. Chemical Hazards: In industrial settings, hand spanners can come into contact with hazardous chemicals like solvents, acids and oils. Inhaling or coming into contact with these substances can cause serious health issues.

Overall, hand spanners are useful tools, but they can also be hazardous if not used correctly. It is important to make sure that the spanners are used properly and with the right amount of force to avoid injury and damage.

Safety Tips while using hand spanners -

Hand spanners are essential tools used by professionals to access and tighten nuts, bolts, and other materials. However, due to the potential of slippage and other hazards, it is important to take safety precautions when using them. Here are some safety tips to remember when using hand spanners:

1. Ensure the correct size spanner is used – Make sure to select the correct size spanner for the job, as one that is too big or too small will not fit properly and can cause the nut or bolt to become loose.

2. Wear protective gloves – Wearing protective gloves when using a hand spanner is essential, as it will help to protect your hands from slipping and causing injury.

3. Position the spanner correctly – Make sure to position the spanner correctly on each nut or bolt, as doing so can help to reduce the risk of slippage and injury.

4. Use additional tools – If the nuts or bolts are particularly tight, consider using additional tools to assist in loosening or tightening them. This will help to reduce the potential of the spanner slipping from your hands.

5. Inspect the spanner regularly – Inspect the spanner regularly for any signs of damage or wear. Damaged spanners can be more dangerous to use, as the jaws may be weakened or distorted, increasing the risk of slippage.

Following these safety tips is essential for anyone using hand spanners. Taking the necessary precautions will help to reduce the risk of accidents or injury.
