CONFAST 1/4 in x 2-3/4 in Hex Head Concrete Screw Anchor - Bit

In this review of the CONFAST 1/4 in x 2-3/4 in Hex Head Concrete Screw Anchor, the bottom line is simple: this box of 100 is aimed at tradespeople and DIYers who need a dependable, ready-to-use concrete fastener with the correct drill bit included. The single biggest reason to buy is convenience combined with consistent performance - each box ships with a matched carbide bit, which helps achieve recommended hole size and improves holding values compared with mismatched bits. The review covers installation, real-world use on block and brick, and who gets the most value from these anchors.

Key Features

• Bit included: Each box contains a properly sized carbide bit, which reduces waste and ensures holes meet the 3/16 in requirement for reliable anchoring.
• Slotted hex head: The hex washer head sits flush on the surface and can be driven with a 5/16 in nut driver for quicker installation on repetitive jobs.
• Self-tapping design: The screw taps its own threads in masonry, eliminating the need for separate anchor inserts and speeding up installs.
• Diamond point: The sharpened point makes starts easier and reduces walking, saving time when driving screws into block or brick.
• Carbon steel construction: The steel body provides the strength needed for structural attachments to concrete, block, and brick in dry environments.

Who It's For

These concrete screws suit contractors, framers, and serious DIYers who frequently fasten wood or metal to masonry and want a bulk option with the correct drill bit included. The 100 per box quantity and included bit make them a practical pick for projects like attaching plates, furring, or mounting 2x4s to concrete block.

Those who need corrosion resistance for outdoor or wet locations should look elsewhere, since the product is specified for dry environments and carbon steel construction; also buyers who only need a few fasteners may prefer smaller pack sizes or single screws.

Pros & Cons
