Thread Locking by BENSELER

Thread locking as a mechanical (in special cases also manual) pre-coating is a process in which BENSELER partially coats the threads to be secured with a liquid locking lacquer. After subsequent drying, a dry, non-slip coating is formed. The task of thread locking systems is to secure thread pairs against loosening or loss. Sealing can also be a desired effect. For this purpose, BENSELER applies the products precote^®, LOCTITE^® or BETEO S-LOK or SCHRAUSI-LOK in different variants. Pre-coated screw and nut locking is a very sustainable process, waste-free and low in solvents. The coatings can be poured and stored and are only activated when the screws are tightened. BENSELER is happy to provide customers with individual and comprehensive advice on which thread locking system is best suited to their specific requirements.

In thread locking by adhesive bonding, microcapsules are crushed by pressure or shear stress when the threaded part is screwed together. The liquid components released as a result are mixed and then harden so that the threads are secured against loosening.

This process is suitable for steel, stainless steel, non-ferrous materials, plastic and all common surfaces. After application, the coatings are pourable and non-slip.

BENSELER adhesive threadlockers comply with DIN 267 Part 27 as well as many specifications of the automotive industry worldwide.

Standard products used are: precote^® -30, 50, 80, 85, 86, 87, -3/-8; 3M; Loctite/Driloc 2040, 2045 and others.

• Reliable thread lock to prevent automatic loosening
• Captive, dry and non-slip
• Bonding and additional sealing function
• insensitive to e.g. oil and grease after curing
• reproducible, defined assembly values
• storable

When securing threads by clamping, a chemical coating (e.g. polyamide patch S-Lok) is partially applied to the threaded part. This application has an inhibiting effect. This prevents the screw from unscrewing and losing itself under load. Nevertheless, the screws can be loosened at any time and can also be screwed in or out several times. After screwing, the clamping lock is effective immediately and does not require any curing time.

The clamp is suitable for steel and stainless steel screws, galvanized iron materials, aluminium, etc. and is an environmentally friendly and cost-effective anti-loss device. Various colors are available.

BENSELER uses precote^® 6, 9, 10, 10-1, 19-2, 19-7, BETEO S-Lok, Schrausi-Lok and BETEO VC-3 clamping coatings.

Depending on the product, the clamping lock complies with DIN 267 / 28 and many automotive industry specifications worldwide.

• Can be reused up to 5 times
• Immediate clamping effect after assembly
• Can be stored for a very long time
• Sealing effect against liquids and gases
• Temperature-resistant from - 50° to + 120°C
• captive, dry and non-slip

BENSELER also uses chemical thread locking coatings for thread locking by sealing. These are applied partially in order to reliably seal thread pairs against gases and liquids. Different products are used depending on the sealing requirements. In contrast to clamping, the sealing effect starts directly during the screwing process.

Sealing is suitable for steel, stainless steel, non-ferrous materials, plastic and all common surfaces. The products used are precote^® 30/-3/-8; precote^® 4, 5, 15, 200; Loctite^®/Driseal 5061.

• Immediate sealing effect against liquids and gases after installation
• No change in the thread friction coefficient
• also suitable for plastics
• captive, dry and non-slip
