1/4" x 3-1/4" Conquest Hex Concrete Screw - 410 Stainless Steel, Pkg 100

The 1/4" x 3-1/4" Conquest Hex Concrete Screw is designed for masonry fastening jobs that call for added length and dependable holding power. Made from 410 stainless steel, it offers a rugged balance of strength and corrosion resistance for interior use and light exterior exposure. The hex washer head gives you a secure drive interface for efficient installation in demanding base materials.

Notice: Pilot drilling is required for use in concrete, brick, or block.

1/4" x 3-1/4" 410 Stainless Concrete Screw Anchor with Hex Washer Head

This length is well suited for securing thicker fixtures to masonry while keeping the workflow simple: drill the pilot hole, clean it out, and drive the screw to seat.

Key Features

  • 410 stainless steel: Built for durability with added corrosion resistance.
  • Hex washer head: Promotes positive engagement for impact drivers and nutsetters.
  • Anchorless installation: Fastens directly into masonry after pilot drilling.
  • Aggressive thread bite: Designed to tap firmly into concrete, brick, and block.

Common Applications

  • Heavy bracket mounting: Secures supports where added screw length helps.
  • Fixture anchoring: Installs plates and bases to masonry surfaces.
  • Metal framing to concrete: Attaches tracks and components to concrete floors or walls.
  • Equipment mounting points: Secures hardware to block and concrete.
  • Outdoor structures: Light exterior fastening with corrosion-resistant material.

Installation Tips

  • Clean the hole thoroughly: Dust buildup can reduce thread engagement.
  • Start slow, then drive: A controlled start helps keep the screw on-line.
  • Seat the head firmly: Tighten to secure the fixture without over-torquing.
