Dynabolt is the brand name for the sleeve anchor
manufactured by ITW/Red Head. The Dynabolt is a sleeve type anchor that
is specified for anchoring into concrete, hollow concrete block,
grout-filled concrete block and brick base materials. Other sleeve
anchors are also available and work under the same priniciples and can
be purchased online.
Dynabolt Sleeve Type Anchor
The Dynabolt sleeve anchor is made up of four different parts-
the split expansion sleeve, a threaded stud bolt or body, nut and
washer. Dynabolts come preassembled and are made from either zinc plated
carbon steel or 304 stainless steel. A number of different head styles
are available. The 1/4" diameter comes in an acorn, flat or round head.
The 3/8" in a hex nut or flat head. The 1/2", 5/8" and 3/4" are only
available in the hex nut head.
Dynabolt Hole Size
When drilling a hole in the base material for a Dynabolt sleeve
anchor, a carbide tipped bit must be used and it needs to meet ANSI
standards B212-15-1994. This will ensure proper hole sizes and holding
values. The hole diameter that must be drilled for the sleeve anchor is
the same diameter as the sleeve anchor being installed.
Dynabolt Features
The Dynabolt sleeve anchor is a light to heavy duty fastener.
These anchors provide full 360-degree contact and reduce base material
stress. When using a Dynabolt anchor, no pre-spotting of holes is
necessary and the sleeve anchor can be installed through the object
being fastened as long as the hole is large enough for the anchor to be
inserted through it.
Dynabolt Alternative
All sleeve anchors work in the same manner and will provide the
same basic holding values as a Dynabolt. The main differences between
different concrete sleeve anchors are price and availability. If you are
going to need sleeve anchors, buy them online as they are less
expensive than buying at other brick & mortar stores. All sizes will
be in stock online as well. Buying online will save you money.
How to Install Dynabolt Sleeve Anchors
1. With a hammer drill, drill a hole in the base material using
carbide tipped drill bits that meet ANSI standards. Make sure that the
bit diameter is equal to the diameter of sleeve anchor being installed.
The hole can be drilled to any depth as long as it exceeds the minimum
embedment requirements for the anchor being used.
2. The hole must be cleaned of any debris left over from the
drilling process. Use a wire brush, compressed air or a vacuum to remove
this debris.
3. Insert the sleeve anchor through the fixture and into the hole
in the base material until the washer is flush with the material being
fastened. Light taps with a hammer may be needed to seat the anchor
properly.
4. Using a wrench, expand the anchor by turning the nut or head 2-3 turns.
Red Head Dynabolt Sleeve Anchors can be used in a variety of base
materials including concrete, concrete block and brick. It is important
to choose the correct diameter and head style for your unique
application. Installing a Dynabolt sleeve anchor can be accomplished in
four simple steps. Buy sleeve anchors online for convenience and to save
money!
