How to Install Bolt with Washer (-SEC) of 90 degree Brackets
■ How to install the 90 degree Brackets for aluminum frames that comes with a set of bolts with spring washers (-SEC)
Compared to other series of sets with bolts with spring washers, this product requires more care when tightening because the bolt heads interfere with each other.
We will introduce how to install it.
STEP 1 Installation sequence
STEP 2 Tightening the hexagonal bolts

Of the two holes, installation will be done through the hole mentioned above.
STEP 3 Adjust the position of the spring washer on the bolt
, the heads of the previously tightened bolts
will interfere and installation will be impossible.


Finally, tighten the hex bolt by twisting it.

In cases where it is difficult to pre-tighten one side, we recommend using the following products.
<Alternatives>
Case 1: When changing the bolts without changing the bracket
HBLFSSW8-SET (changing the bolt and nut set applicable for additional work)
Case 2: When changing the bracket without changing the bolt with spring washer
HBLFSH8-SEC (changing to a one-sided oblong hole bracket)
The hole on one side of the bracket is an oblong hole, so even if a hexagonal bolt with an integrated washer is used, the bolt head will not interfere with installation.
