Description / Price
Brass wall anchor, special brass anchor knurled with a slightly conical running internal thread of different metric thread sizes, outer surface / grooved. Four sizes:
DM 06025, l = 25 mm, f. M6, Drill-d = 8 mm - Price
DM 08030, l = 30 mm, f. M8, Drill-d = 10 mm - Price
DM 10030, l = 30 mm, f. M10, Drill-d = 12 mm - Price
DM 12040, l = 41 mm, f. M12, Drill-d = 16 mm - Price
For repeated, if necessary, releasable fastening of wall holders of the WM series (metric threaded shaft). In very solid substrates such as concrete, lightweight concrete, clinker and limestone. Used also in brickwork. Please, if necessary, use the general information on anchor technology.
Please take note the section about " Drilling!" In concrete, natural stone, and bare walls, brass anchors are usually set flush with the outer surface, in other substrates, a sinking is recommended of 1 - 2 cm. Do not put the anchors into joints, but only directly into the stone. Turn the set screw out of cross holders.
Drill hole diameter equal to or slightly greater than the outer diameter anchor. Minimum depth of the borehole is calculated from sinking depth plus anchor length plus a rear clearance from 0.5 to 1 cm. Blow / brush out drill hole to achieve optimal adhesion. Oil threaded shaft in the rear, screw in metal anchors such an extent that the spreading effect happens, the shaft including brass plugs but still can be inserted easily into the borehole. Is the drill hole too tight ? It can be widened by drilling with lateral pressure against the borehole walls.
Then slide the wall bracket with screwed metal anchor into the drill hole, possibly also with very light hammer blows 'to adjust.' Insertion of WM 10080 and WM 10081 so that the anchor wall is flush with WM 08080 and other eyelets so that the wall mount survives outside to about 1 - 2 cm. A narrow or wide hole can be corrected by changing the pre-post spreading of the brass anchor with the threaded shaft by a little further rotating the shaft in or cut back somewhat, in the other case.
If the components together with anchors are inserted, then the wall bracket is rotated further into the anchor, with cross holders transversely inserted through the grooves by means of screwdriver . If the dowel 'spins', therefore rotates and is not 'engaged' keep, the threaded shaft at a slight angle and push the dowel side against the borehole wall and turn it until the plug engages. The resistance during the further screwing in then increases rapidly, crunching noises indicate a successful screwing in. After about 5-10 revolutions sufficient anchoring is reached, the further fastening operation depends on the kind of the wall holder (possibly support plate clamp, etc.).
The brass plug develops strong expansion forces in the rear, the grooved portion is therefore are not suitable or only in a very limited way for porous and brittle substrates such as sandstone, aerated concrete (ie concrete 'gas', 'Ytong'), etc. If in doubt, it is useful to not set the anchor flush, but more deeply inserted into the supporting wall layer to prevent spalling, cracks etc. Otherwise, an expansion free anchorage with composite mortar is preferable.
Once set, brass anchors who've been spread, should not be used again, otherwise during new assembly the broken anchor my be unnoticed as cracked due to the fragility of brass.
