Unilock’ thread-locking screws adopt the raw materials for coating from internationally renowned brands such as Loctite and 3M to provide our customers thorough service of the finest quality.

LOCTITE has received the Q1 medal of excellent quality from Ford and complied with the BS5750 / ISO 9001& ISO 9001 QA certification. We have also obtained the certification of excellent supplier from Black& Decker, acknowledgement from the Ministry of Defense in the UK and passed the examination of British Aerospace Bureau, that comply with the world regulation of OEM technology.

With daily rapid progress, do you know the level of thread-locking technology at present?

Different functions of use and glue for processing
Sorted grades and colors for provision of different thread-locking torque
Pollution-free and water solubility that comply with future requirements of environmental protection
Insistence on quality and never processing with substitutes

Application test and performance of correct thread-locking torque according to the data
Coating process in advance for reduction of manufacturing duration and cost
360° annular coating for even application, zero thread damage and leakage stoppage
The characteristics of Unilock’s repetitive fixed thread-locking screw
The soft material and minor tightening torque do not damage the work piece. In particular, the performance is better than nylon glue in case of small screws (M1~M4).
The low solidification point with processing temperature of approximately 80℃ ~ 120℃ does not affect the screw material and surface treatment, thereby ensuring product quality that is better than the conventional processing method of directly heating the screws with high frequency.
The declination of gripping force for every repetition is smaller even for the 360° coating torque.

The description of using Unilock’s repetitive fixed thread-locking screw

The coating angle must be 360° to ensure the same thread-locking torque at the specified angle.
The gluing position in principle starts from the reserved space of 0-1 pitch (no glue applied) from the front end, and processing according to client’s drawing can be executed when necessary.
The glue width in principle shall preferably be more than ‘4 pitch’ and further processing can be executed according to client’s design, where the torque must be determined separately.
Glue adhesion: The glue must not detach in whole loop during the torque test.
