Best 1/4-20 X 1-3/4 Wedge Anchors for Concrete
For a 1/4-20 x 1-3/4-inch wedge anchor, the closest listed matches are the MIGHTY FASTENERS 316 stainless steel anchors and the ALBANYCOUNTYFASTENERS 304 stainless steel anchors. The Mywish set also matches the stated dimensions, though its listing does not specify a 1/4-20 thread. The two longer options below are alternatives, not exact size matches. None of the supplied product details confirms a 1-1/8-inch minimum embedment, so verify that requirement with the anchor manufacturer before installation.
| Product | Best for | Size match |
|---|---|---|
| MIGHTY FASTENERS 316 SS, 25 pack | Moisture-exposed locations | 1/4-20 x 1-3/4 inches |
| ALBANYCOUNTYFASTENERS 304 SS, 100 count | Bulk concrete fastening | 1/4-20 x 1-3/4 inches |
| Mywish 304 SS, 10 pack | Small projects needing this length | 1/4 x 1-3/4 inches; thread pitch unlisted |
| Stainless steel anchors, 20 pack | Projects needing a longer anchor | 1/4 x 3-1/4 inches |
| Wensilon galvanized anchors, 10 pack | Projects needing a longer carbon-steel anchor | 1/4 x 4 inches |
MIGHTY FASTENERS 316 Stainless Steel Anchors
This 25-pack is the most directly specified match for a 1/4-20 x 1-3/4-inch search. The listing identifies both the thread size and overall length, and describes a wedge expansion mechanism that presses against the drilled-hole walls as the nut is tightened.
Best for: Buyers fastening compatible fixtures or equipment to solid concrete in damp, outdoor, or corrosive environments. The 316 stainless steel construction is the stated reason to choose this option for moisture exposure.
Limitation: The supplied details do not state a minimum embedment depth or load capacity. Confirm both for the intended installation, especially if 1-1/8 inches is a required embedment.
ALBANYCOUNTYFASTENERS 304 Stainless Steel Anchors
This 100-count option is listed as 1/4-20 x 1-3/4 inches and is designed for installation in solid concrete. The product description names uses such as shelving, railings, signs, ductwork, electrical pipe, and light fixtures.
Best for: Buyers who need a larger quantity of the specified size for repeated concrete installations. It is a clear dimensional match, making it easier to compare against a 1/4-20 requirement than listings that omit thread pitch.
Limitation: The available features do not provide an embedment-depth specification, load rating, or corrosion-environment guidance. Check the product documentation before choosing it for a demanding application.
Mywish 304 Stainless Steel Wedge Anchors
The Mywish 10-pack is listed as 1/4 x 1-3/4 inches and made from 304 stainless steel. Its description identifies solid-concrete uses that include fixtures, beams, machinery, and handrails, and says the anchors are intended to provide tensile and shear resistance.
Best for: Buyers seeking the listed diameter and length in a smaller pack for concrete construction or renovation. The 304 stainless material is described as offering improved corrosion resistance in humid or outdoor environments.
Limitation: The listing does not specify a 1/4-20 thread pitch. Confirm thread compatibility before purchase if your fixture or nut requires that exact thread. The seller notes that slight magnetic properties may occur from manufacturing.
Stainless Steel 1/4 x 3-1/4-Inch Anchors
This 20-pack has a 1/4-inch diameter but measures 3-1/4 inches long, so it is not a match for a 1-3/4-inch anchor. The listing describes stainless steel construction and use in solid concrete or cement.
Best for: Buyers whose project calls for a longer anchor and who have checked the required fixture thickness and embedment. It may be useful as a size alternative when the shorter anchor does not meet the installation plan.
Limitation: The listing says not to use these anchors in block or brick. Thread pitch and minimum embedment are not provided in the supplied details.
Wensilon 1/4 x 4-Inch Galvanized Anchors
These 10 anchors are 4 inches long, substantially longer than the requested 1-3/4-inch size. The listing describes galvanized carbon steel and says each anchor comes with a nut and washer already in place. Its stated uses include attaching items to concrete, sloped buildings, metal plates, steel, and wood.
Best for: Buyers who specifically need a longer galvanized carbon-steel anchor and can verify that its dimensions suit the fixture and base material.
Limitation: This is not an exact size match. Thread pitch, minimum embedment, and suitability for a particular load are not stated in the supplied product details.
Buying Guide
Does 1-1/8 inches refer to embedment depth?
Confirm whether 1-1/8 inches means minimum embedment into the concrete, hole depth, or another measurement in your project specification. Anchor length and embedment depth are different measurements. The supplied product information does not verify a 1-1/8-inch minimum embedment for any listed option.
How do you confirm the size and thread?
Compare diameter, thread pitch, and overall length with the fixture and nut requirements. The MIGHTY FASTENERS and ALBANYCOUNTYFASTENERS listings explicitly state 1/4-20 x 1-3/4 inches. Mywish lists the diameter and length but not the thread pitch, so verify it before buying.
Which material should you choose?
Choose based on the installation environment and the product documentation. The 316 stainless option is described for enhanced corrosion resistance in moisture-exposed or corrosive conditions. The 304 stainless options are described as corrosion-resistant, while Wensilon uses galvanized carbon steel. These descriptions do not replace application-specific guidance.
What base material is appropriate?
Wedge anchors are intended for solid concrete. Do not assume they are suitable for brick, hollow block, or other masonry just because a listing uses the word “masonry.” One product listing explicitly warns against using its anchors in block or brick. Check the manufacturer’s instructions for the exact substrate.
What installation details should you check?
Verify the required drill-bit diameter, hole depth, minimum embedment, fixture thickness, tightening instructions, and allowable load in the manufacturer’s documentation. Drill and install according to those instructions; do not infer a load rating from anchor dimensions alone.
Frequently Asked Questions
Is 1/4-20 x 1-3/4 the same as a 1/4-inch anchor?
Not necessarily. “1/4-20” specifies a 1/4-inch nominal thread diameter and 20 threads per inch. A listing that only says 1/4 inch may not confirm that thread pitch.
Does a 1-3/4-inch anchor provide 1-1/8 inches of embedment?
Overall length alone does not confirm embedment. Fixture thickness, anchor design, and installation requirements affect the usable depth. Check the manufacturer’s specifications.
Can wedge anchors be installed in brick or block?
Do not assume so. The listed products are described for solid concrete, and one listing specifically says not to use its anchors in block or brick.
Which listed product is the closest match to the requested size?
The MIGHTY FASTENERS and ALBANYCOUNTYFASTENERS options explicitly list 1/4-20 x 1-3/4 inches. The Mywish product lists the diameter and length but does not state the thread pitch.
