Locking Elements
Locking Elements
In machinery construction or product assemblies, locking elements are used to perform a restraining role in the mechanical assembly.
We offer a wide range of Locking Elements. These include locking Pins, Washers, Circlips, Lock Nuts, Shackles and Links, etc. They perform various functions all related to locking as part of a mechanical assembly. They are very useful components that are used to compensate for vibration, prevent lateral movement, constraint members, provide alignment etc.

Snap Rings DIN 9925 DIN 9926
Starlock Push Fastener
Available in Spring Steel and Stainless Steel – 1.4122
Locking Washers
Bolt and Nut assemblies tend to become loose due to vibration and torque. Lock washers are designed to prevent bolts and nuts from turning, slipping and coming loose. There are various types and models with each type suitable for a particular application. The types available with us include the following.
Split Lock Washers – DIN 7980 DIN 127B
Spring Steel
Stainless Steel AISI 301 and AISI 316
Titanium Grade 2
Disc Spring Washers – DIN 2093
Stainless Steel AISI 301
Star Washers – DIN 6797A External
and DIN 6797J Internal
Stainless Steel AISI 304 and AISI 316
Serrated Safety Washers Type S – Schnorr Type
Stainless Steel AISI 304
Afnor Contact Washers – NF E-25 511
Stainless Steel AISI 304 and AISI 316
Conical Spring Washers – DIN 6796
Stainless Steel AISI 304 and AISI 316

Links and Shackles
Locking Nuts
Lock nut, also referred to as a nylon-insert lock nut, polymer-insert lock nut, or elastic stop nut, is a kind of locknut with a nylon collar insert that resists turning.
Lock threaded assemblies while protecting against vibration, corrosion and galling.
A threadlocker is an anaerobic adhesive used on threaded metals that cures at room temperature in the absence of air. The adhesive completely fills the gaps between mating threads to lock and seal the threaded assembly.
Benefits of Using Threadlockers
- Locks mating threads to prevent loosening from vibration & shock
- Seals against fluids & corrosion
- Provides lubricity to achieve controlled torque during assembly
- Works on active metals (e.g., brass, copper) as well as passive metals (e.g., stainless steel, plated surfaces)
- Resists extreme temperatures
- Applies easily and cures rapidly
Hose Clamps
Interlocked worm gear hose clamps help secure many types of hoses, including pneumatic and exhaust hoses.
A general-purpose hose clamp is interlocked to prevent shearing, These Clamps mainly consists of four components viz. the captive screw, housing, band & underlap. When the screw is turned, it acts as a worm drive pulling the threads of the band, causing the band to tighten around the hose.
These clamps are used for multiple applications viz. Automobile, Heavy engines, Irrigation, Marine, Railways, Tractors, Pneumatic connections, Electrical cable joints, Chemical, pharmaceutical and other industrial usages.
