Reliable Steel Distributors is a specialized manufacturer of high quality washers in India . Washer, machine component that is used in conjunction with a screw fastener such as a bolt and nut and that usually serves either to keep the screw from loosening or to distribute the load from the nut or bolt head over a larger area. For load distribution, thin flat rings of soft steel are usual.
They go on the thread end of the screw, inside of the material, so… The lock washer is used to basically press into the material to grip onto it. The flat washer is used to create an even distribution of pressure from the nut. Both also create a larger holding surface for the nut and bolt to connect everything.

Backup Rivet Washers
Rivet backup washers are used to create a larger install diameter giving the rivet a better hold and more support. Backup washers can help to prevent pull-through of a rivet.
Belleville Conical Washers
Belleville conical washers are a type of washer that adds extra tension to a fastener assembly. They are commonly used in stacks to increase the load, deflection or both to an assembly depending on the stack. These washers can be considered lock washers because they add tension and absorb vibration to an assembly.
Dock washers are heavy duty washers, often used to build docks. Also used in heavy duty construction where a thick washer is needed, dock washers are similar to fender washers with a small inside diameter hole.
Fender washers are round washers with a small inside diameter hole. Fender washers are used to prevent pull-through and provide a greater bearing surface under the fastener.
Fender Washers - Extra Thick
Fender washers are round washers with a small inside diameter hole. Extra thick fender washers are thicker than standard fender washers and are used to prevent pull-through and provide a greater bearing surface under the fastener.
Finishing Cup Washers
Finishing cup washers form a cup for the head of the screw or fastener to fit in, creating a finish flush with the top of the head. Used for finishing, cup washers are shaped like a cup.
Flat washers are round outer diameter thin plates with a center hole punched to the size of the bolt or screw. Flat washers are used to distribute loads of threaded bolts, screws and nuts evenly as the fastener is tightened.
Flat Washers - Extra Thick
Extra thick flat washers thicker than standard flat washers. These washers are round outer diameter thin plates with a center hole punched to the size of the bolt or screw. Flat washers are used to distribute loads of threaded bolts, screws and nuts evenly as the fastener is tightened.
Flat Washers - Military Standard
Military standard (MS) flat washers go through extensive inspection for chemical, physical and dimensional qualities. MS washers must meet specific inner diameter and outer diameter specifications.
Flat Washers - 900 Series
Flat washers in the 900 series are round and thinner than a standard flat washer with a smaller inside and outside diameter.
Lock Washers - Split Ring
Split ring lock washers are used to prevent nuts, bolts and screws from vibrating loose. These washers are rings which are split at one point and bent into a helical shape
Lock Washers - High Collar
High collar lock washers are designed to fit under the head of a socket cap screw. Split ring lock washers are used to prevent nuts, bolts and screws from vibrating loose. These washers are rings which are split at one point and bent into a helical shape.
Lock Washers - External Tooth
External tooth lock washers are used for locking and tension. Round washers with teeth on the outside, used for maximum holding power. Must be used with fasteners with adequate head diameter.
Lock Washers - Internal Tooth
Internal tooth lock washers are used for locking and tension. A round washer with internal teeth, designed to prevent a nut or screw head from loosening with the strut action created by the teeth.
NAS washers are round washers with a smaller inner and outer diameter. Often used in military applications because of the strict measurement specifications.
Neoprene EPDM Washers
Round washers that are slightly beveled with a neoprene lining. Often used with sharp point and self-drilling TEK screws to make a watertight seal around the screw or metal roofing or siding.
Structural washers are thick and strong, built for heavy duty applications such as construction. These washers can be found in steel beams and girder fastener assemblies.
Square washers are square in shape and may be flat on both sides or flat on one side and beveled on one side. Often used with square head bolts, square washers prevent pull through and provide a larger surface area and greater hold than standard round flat washers.
Washers are usually metal or plastic. High-quality bolted joints require hardened steel washers to prevent the loss of pre-load due to brinelling after the torque is applied. Washers are also important for preventing galvanic corrosion, particularly by insulating steel screws from aluminium surfaces.
Fasteners are used to mechanically join two or more objects together, either permanently or non-permanently. There are many different types of fastener, each with their own purpose.
Not all materials require the use of washers. But for wood and other relatively soft materials, washers are useful to protect against stress-related damage when the threaded fastener is driven into the material.
