Spring dowel pins are incredibly high strength pins that come with high durability and a long life expending for several decades. They are manufactured with a diameter slightly greater than the drilled hole through which it is to be inserted. The elasticity of these pins then applies a radial force across its length. Pins contain a slot that allows compression when inserted into the hole. The spring pin is used to assemble the parts without a screw. This makes it one of the most valuable and straightforward fastening systems in the market. At HELLARY it is available in stainless steel, carbon steel, and alloy steel.

Forged Eye Bolts
Hexagon bolts are also known as hex cap screws or machine bolts. have hexagonal heads and machine threads for use with a nut or in a tapped hole. Hexagon screw head bolts are made from a variety of materials to accommodate the wide range of applications in which hex cap bolts are used.
High Tensile Bolts
Anti-theft bolts are primarily used in industries where robust permanent security fixings are required. Therefore, it is widely used in power transmission towers like electric and mobile towers. Anti-theft bolts have their application as security screws in solar panels, jails, security fencing, etc. where temper proofing is a vital feature.

Socket Head/Allen Bolt is a bolt with a hexagonal socket in its head that is designed to be used with an Allen wrench. The Allen bolt is integral to the crank and remains in it when the crank is removed from the spindle. The primary advantage of Allen bolts is that they are perfect if you have a bolt thatâ??s down inside a narrow opening. You can stick the Allen key down into the hole and do up the bolt. A socket cap screws are machine screws with a cylindrical barrel-shaped head containing a hexagonal socket. The head has a smaller diameter than most other machine screw heads, typically just 1.5 times the nominal thread diameter. Socket cap screws may also be referred to as a socket head cap screw, a cap head socket screw, or a hex socket head screw.
A Square Head Bolts are low or medium carbon steel, externally threaded bolt, 1/4" diameter or larger, with a trimmed square shaped external wrenching head. Square head bolts were the industry standard prior to hex bolts taking over. A square head bolt has a distinctly shaped head that makes it ideal for working in blind areas. Square head bolts are now normally used in rustic look applications. With the proper tools, tightening a square head bolt is easy even when the fastener is out of your line of vision. The head design of square head bolts enables an easier wrench grip for nut tightening. They are usually used in new construction to mimic an older aesthetic or in railway applications. Square head bolt design enables an easier wrench grip for nut tightening. They are usually used in new construction along with square plate washers and taper washers. These Bolts worked really well in the railroad industry, where supervisors could check that all bolts were on based on whether the head lined up with the tie. It is common in the railroad industry, on electrical panels, and in furniture manufacturing.
A U-bolt is a bolt in the shape of the letter U with screw threads on both ends. U-bolts have primarily been used to support pipework, pipes through which fluids and gasses pass. U-bolts are also used to hold ropes together. Its main application in the automobile industry in which U-bolt provides the force required to clamp the leaf spring and related components firmly together. In addition to the leaf spring, these components include the top plate, axle seat, axle, and bottom plate.
Wedge Anchor Bolts
Anti-theft nuts, also known as anti-removal screws, are used in many outdoor products to ensure the safety of mechanical components and fastening parts. CBH offers you the latest products with excellent anti-theft performance in this high-tech world.
Flange lock nuts are one-piece, all-metal prevailing torque hex flange nuts. The protruding circular flange increases the nut's bearing surface allowing them to be used with irregular and oversized holes. These screws secure the fastener by applying a downward force on it. Another way in which these nuts secure bolts is by creating extremely tight friction between the nylon and the threads. The main common application of these nuts is they can with stand extreme amounts of torque and therefore, can be used in high strength and industrial applications include lawn and garden equipment and truck manufacturing. It can also protect oil or other liquids from slipping through. They are especially suitable for applications where there are constant movements and vibrations - flanged NY lock nuts can absorb the impact without damaging the threads of the fasteners. HELLARY provides these nuts in different materials and finishes like stainless steel, carbon steel, and alloy steel.
A lock nut is also called a stiff nut and these nuts help to resist loosening under vibration and torque. After inserting one nut onto the end of the bolt, they would place a second nut on the bolt. There are many types of lock nut but they can be broadly divided into those which use friction to prevent loosening. While the use of two nuts is effective at preventing vibration-related loosening, itâ??s not cost-effective for manufacturing companies that perform large-volume production operations, and lock nuts are also described on the basis of some form of positive locking device. There are several types of lock nuts, the most common of which include metal lock nuts and nylon insert lock nuts. Traditional nuts simply consist of a basic threaded hole, so constant exposure to vibrations can knock them loose from the bolt-on which they are placed. Locknuts protect against loosening, however, by featuring a design that increases the nutâ??s resistance to vibrations. In comparison, nylon lock nuts feature a layer of nylon material covering the interior threading. When a nylon lock nut is placed on a bolt, the nylon fibers expand to grip the bolt.
Slotted/Castle nuts are pre-drilled, they can be used without a pilot hole. These nuts are slotted, allowing them to be installed and removed using screw drivers. It is used primarily as safety nuts, these nuts are slotted to receive a cotter pin or wire which passes through a drilled hole in the bolt and locks it. When a castle nut is applied to a threaded section, it is tightened so that its slot is aligned with a predrilled hole in the bolt or threaded rod, into which a cotter pin, split pin, a lock wire or a spring pin is typically inserted to stop the nut from rotating. Sometimes they are used on trailers too. They are also used as hub nuts that hold the driveshaft within the wheel hub assembly. At HELLARY it is available in stainless steel, carbon steel, and alloy steel to bear more wear and tear while also making it more corrosion resistant.
