BIS Certification For Wrought Aluminum Alloy Bolt And Screw Stock For General Engineering Purpose IS 1284
Wrought aluminum is defined as an
alloy that has been subjected to mechanical working by processes such as
rolling, extrusion or forging. In contrast, cast aluminum is formed by
pouring molten aluminum into a pattern or die.
Screws
are a versatile fastener, which makes them a favorite choice. They provide a
secure grip thanks to their threads and they meet the needs of numerous
do-it-yourself (DIY) projects. They come in a variety of sizes and types for wood, metal, drywall and even concrete
applications.
Bolts
provide the best holding strength compared to screws and other fasteners. Thanks to their
threads, bolts can provide an unparalleled level of holding power. They do
require a nut and a washer for their installation. The
washer helps to spread the load over a larger surface area, which reduces the
wear and tear as well as the loosening of your bolt over time while the nut
secures the bolt in place.
Like
screws, bolts come in many sizes and
types.
They’re also usable with several materials ranging from metal and wood to
concrete.
Installing
a bolt requires a handheld or pneumatic wrench to remove or install it.
Compared to screws, bolts can be easier to remove. The benefit of a pneumatic
wrench is that it provides much more torque than a handheld tool, which makes
your job easier.

Application :
bolts provide a tremendous
amount of holding strength whereas screws
offer a middle-ground for holding power. Light to medium construction projects,
like for fencing or framing, are best for screws. Your heavy-duty projects are
best for bolts. Bolts are also best when the finished project is meant to be
assembled and disassembled easily.
Materials That Typically Require
Screws:
- Plywood
- Press
board
- Drywall
- Sheet
metal
- Deck
planks
Materials That Are Usually Best for
Bolts:
- Concrete
- Studs
- Beams
There
are some materials that could require either a screw or a bolt assembly for
fastening. For example, a 2” x 4” might be best fastened as a stud that is part
of the framework for a wall using screws, but for an application like a deck
assembly, bolts are likely a better choice. Be sure to consider the load being
put on the fastener in combination with the material when choosing between
bolts and screws.
