Once installed, this part is tamper-resistant. Sometimes called Concrete Metal Hit Anchors, Hammer Drive Anchors are used for fastening to concrete, brick or block, and driven by hammer. 99Hammer Drive Anchors are hardened steel nails embedded in a cylindrical steel base, similar to Drive Pin Anchors except for the composition of the base. 8) under stresses and conditions that represent the intended use.Concrete Wall Anchors for TV Wall Mount Installation Suitable for Concrete Wall or Brick Wall Installation Plastic Anchor Bolts 10X50mm White 6pcs MD5751 by Mounting Dream 4.5 out of 5 stars 29 6.99 6. For other anchor bolt configurations, including post-installed anchors, design loads are determined from testing a minimum of five specimens in accordance with Standard Test Methods for Strength of Anchors in Concrete and Masonry Elements, ASTM E488 (ref.
There is a small shoulder at the top of the base. This is a true fastener, not an anchor SELF-THREADING CONCRETE ANCHOR GUIDE HOW ANCHORS WORK Set with a hammering action.Drive Pin Anchors, also called Nylon Nails or Nylon Nail-It Anchors, are hardened steel nails embedded in a cylindrical nylon base. Uses the mechanical advantage of screw threads to obtain high expansion pressure. Bolt Size/ Hole Size Types Shell Types Set with a wrench. Zinc anchors are malleable and compress under high loads.
As it expands, the outer wall flows into any irregularities in the hole wall, enabling correct setting in imperfect holes.Machine Screw Anchors are female concrete anchors used to anchor into brick , block , or concrete, and have internal machine screw threads. They are used where strength requirements are not as great as when shields are used, and are not threaded internally.Wood Screw Lead Anchors can also be used in solid masonry and concrete, and are used for light, shallow hold anchoring. The J-bolt prevents the wall from rising or sliding off the foundation.Wood Screw Lead Anchors are wedged into a hole and then expanded for a tight fit with the insertion of a wood screw or similar item. Drive Pin Anchor diameter will be equal to the hole size.In residential construction, 1/2-inch diameter J-bolts are typically utilized to anchor walls to concrete. Drive Pin Anchors come in two different head styles: round and flat. Drive Pin Anchors are not recommended for structural or ceiling applications.
The user threads a screw, or thread-ended hook, through the Hollow Wall Anchor, then pushes it through the wallboard into the hollow space in the wall. The two-piece tubular shield in either version contains a wedge shaped nut at one end, a wedge shaped hollow cone at the other end and is held in place by two spring bands. The expansion at both ends of the shield spreads the anchored load throughout its lengthHollow Wall Anchors (Molly Screws, Molly Bolts)Also called molly bolts or molly screws, hollow wall anchors provide a cheap, fast method for attaching heavy items to drywall. The drop-in anchor requires a setting tool for expanding the anchor.Expansion shields may be single or double piece design. Both are inserted for shear loads or where the bolt may be under side pressure or vibration. Expansion shields consist of a nut, a cone and a tubular shield that are put together as a single unit. Drop-in anchors are a female mating part anchor with coarse threads.
A blue xylan coating (comparable to Stalgard coating) offers longer life and enables easier driving.
