Unbrako Durlok® self locking, anti vibration hex head flange bolts. They are serrated flanged hex head bolts, that may be paired Along with the Unbrako Durlok® self locking serrated flanged nut. They both of those Possess a superior tensile energy of twelve.9 and a black oxide/self coloured finish. These hefty obligation fasteners are well suited for conditions where vibration and jarring occurs and the place the joint is subject to significant hundreds.
They are very easy to hold in metal and provide steadiness additionally strength to ensure that an object is often quickly pulled out or lifted with the help of rope. Eyebolt screws are Typically utilized as being a connection point for anchoring, pulling, pushing, or hoisting programs.

Durlok® Fasteners can be used at substantial temperatures as many as 300°C.
A well-liked and interesting socket head screw using an integrated flange featuring a wider head for bolting softer resources. Ordinarily made use of wherever aesthetics are important, or wherever a reduced profile domed finish is needed.
Used in purposes where the bolts have to be routinely tightened and loosened, negating the need for tooling. With substantial wings They may be snug for steady handling. A2
