The Titen HD Washer Head is a high-strength screw anchor for use in cracked and uncracked concrete, as well as masonry.

The washer-head design is commonly used where a minimal head profile is necessary. The 12mm x 150mm is suitable for use in sill/bottom plate applications, and the washer head's low installed profile means modular wall and floor systems can be installed on top with no need for notching the wall framing to accommodate the anchor.

Material

Carbon Steel

Finish

Mechanically Galvanised

Features & Benefits
  • Designed for 12mm hole size to match the anchor size
  • No special drill bit required — designed to install using 12mm masonry drill bit
  • The anchor's 6-lobe drive eases driving and is less prone to stripping. For added convenience, a 1/2" socket adapter and two T-50 drive bits included in each box
  • Removable — ideal for temporary anchoring or applications where fixtures may need to be moved
  • Washer head allows screw anchor applications incompatible with a hex head
  • Available in M12 diameter 
Installation
  1. Drill a hole in the base material using a carbide drill bit the same diameter as the nominal diameter of the anchor. Drill the hole to the specified embedment depth plus minimum hole depth overdrill to allow the thread tapping dust to settle.
  2. Blow it clean using compressed air. (Overhead installations need not be blown clean.) Alternatively, drill the hole deep enough to accommodate embedment depth and the dust from drilling and tapping.
  3. Insert the anchor through the fixture and set anchor with Mid Torque (300- 400NM) using an Impact Wrench and TX-50 bit.
  4. Tighten the anchor into the base material until the washer head contacts the fixture.

Caution

  • Holes in metal fixtures to be mounted should match the 18mm diameter.
  • Use a Titen HD screw anchor one time only — installing the anchor multiple times may result in excessive thread wear and reduce load capacity.
  • Do not use impact wrenches to install into hollow CMU.
  • Manual installation is not allowed.
  • Oversized holes in base material will reduce or eliminate the mechanical interlock of the threads with the base material and reduce the anchor’s load capacity.
Applications
  • Bottom Plate Application
  • Structural Insulated Panel Systems (SIPS)
  • Fire Door Frame to Precast Concrete 
  • Machinery and Equipment
  • Concrete Formwork and Bracing
  • Where low profile head is required
  • Applications for Screw Bolt, Screw Anchor, Expansion Anchor, Stud Anchor, Safety Anchor, Wedge Anchor, Sleeve Anchor

Compliance
