Weld Nuts
A permanent system of fixing a nut, where the nut projections are resistance welded on to the component.
Types of Weld Nuts
Valve Tappet Nut
This nut is used to lock the valve tappet screw to the rocker arm. The speciality of this nut is - high thread to face perpendicularity & accurate thread sizing. It is made to customer specification.
Special Nuts and Parts
Rivet Nuts
Nuts crimped in sheet which is punched in the shape required. Ideal for use on pre painted sheet.The nut can also act as a rivet, where sheets of dissimilar material are riveted together and then another sheet assembled with bolt or screw.
Assembled Washer - Nut
Nut fitted with washer. Can replace a combination of Nut and washer.
Lock Nuts
In PT nut, the locking is done by deforming part of the threads. Used where permanent locking required. It is not reusable. 'U' nuts are also a type of locking nut , which has high reusability and high heat withstanding capacity.
Types of Lock Nuts
Flange & Serrated Flange Nuts
These nuts are integral nut and washer. Saves time, energy and money when used — especially on assembly lines. Additionally, the flange nuts with serration have higher opening torque than plain flange nut.
Clutch Cable Nut
Clutch Cable Lock Nut are used to manually adjust the brake system either tightening or loosening purpose.
Cap Nuts
Nut with sheet metal cap, Used to cover ugliness of a protruding bolt and make it more aesthetic.

Types of Cap Nuts
Plunger
It is used in solenoid coil assembly and which is located on top of the starter, The Plunger – A mechanism that gets pulled into the solenoid's electromagnet, moving the contact disc and creating a circuit to spin the motor. It also pushes the drive pinion into the flywheel. The Signal (S) Terminal – An input connected to the ignition switch.
Cam Brake
Cam brake is a crucial component of the rear drum brake system in two wheelers, which converts the lever's mechanical input into outward movement of the brake shoes to create friction against the brake drum and slow the wheel.
Weld Pin Nuts
A weld pin nut is a type of fastener designed to weld to another component in an assembly. Weld pin nuts can replace sheet metal screws in thin sheet metal applications. Once welded, they form a powerful bond.
Switch Housing
A starter solenoid is an electromagnet which is actuated to engage the starter motor of an internal combustion engine. It is normally attached directly to the starter motor which it controls. Its primary function is as the actuating coil of a contactor which connects the battery to the starter motor proper.
| Dia. | 30 ~ 55 mm |

| Length. | 35 ~ 60 mm |
Weld Pin Solid
Weld pin is similar to Weld Screw / Bolt but no thread in pin portion, Pin dia acts as a locator which helps in easy assembly to sheet metal part.
| Dia. | 5 ~ 30 mm |

| Length. | 8 ~ 55 mm |
Weld Bush
Weld bushes are generally used to guide locating pin (or) moving pin, Bushes are having Projection legs which is helping to connect assembly part through welding.
| Dia. | 5 ~ 30 mm |

| Length. | 8 ~ 55 mm |
Shaft
Armature Shaft
Rigid rod that supports and rotates the armature core and commutator, which transmits mechanical power from the prime mover to the load equipment.
| Dia. | 9 ~ 15 mm |
|
|
|
| Length. | 70 ~ 150 mm |
Output Shaft
The output shaft of a vehicle's starter motor is the shaft that has the pinion gear attached to it. Its main application is to engage with the engine's flywheel to spin the crankshaft and start the combustion cycle. After the engine starts, the pinion gear retracts from the flywheel to prevent damage.

| Length. | 15 ~ 170 mm |
Bushes
The bush is press fitted into the inner plates which forms the inner link assembly. The pin is press fitted in the outer plate which passes through the bush bore of the inner link assembly.
Rollers
The rollers allow the chain to move more smoothly over the sprockets, reducing wear & tear on both the chain & the sprockets.
