Technical Information of 90 degree Brackets

■ Perpendicularity of 90 degree Brackets

Please check the squareness tolerance table for the bracket's squareness .

■ 90 degree Brackets allowable load concept

As shown in the left figure, two frames are set up, a frame is placed between them, and two 90 degree Brackets are attached underneath, and the allowable load per unit is shown. The allowable load
here indicates the load at which the 90 degree Brackets can maintain its position (without breaking or slipping) when all mounting holes on the bracket are fixed with bolts and a load is applied.

How to Install the Washer and Bolt Set (-SEC) of 90 degree Brackets

■ How to install HBLFSN8-45-SEC, which is a set of the spring washer bolt for the aluminum frame bracket HBLFSN8-45

This product requires more care when tightening than other series of spring washer bolt sets, as the bolt head interferes with the bolt.
We will introduce how to install it.

STEP 1 Installation sequence

STEP 2 Tightening the hexagonal bolts

Tighten the hexagonal bolt securely. 8-45 series (groove width 10 mm) - for single row grooves - inverted bracket with protrusion: Related images

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

Then, press down on the spring washer part of the bolt with your hand.If you leave it in this state when you try to tighten the remaining bolts
, the heads of the previously tightened bolts
will interfere and installation will be impossible. 8-45 series (groove width 10 mm) - for single row grooves - inverted bracket with protrusion: Related images

STEP 4 Tighten the hex bolt.
Finally, tighten the hex bolt by twisting it.

As shown above, care must be taken when attaching the washer to the HBLFSN8-45-SEC of the 8-45 series.
In cases where it is difficult to pre-tighten one side, we recommend using the following product.

<Alternative>
Change the bolt without changing the 90 degree Brackets
