The Simpson 5/8-in. Wire Hole-Cleaning Brush Head is engineered specifically for cleaning drilled holes prior to adhesive anchor installation. Designed by Simpson for use with SET-3G and AT-3G adhesives, this wire brush head enables proper hole cleaning with fewer brush strokes at embedments up to 20 times the anchor diameter - helping ensure a clean, adhesive-ready hole for reliable anchor performance. Note that a T-handle and any extensions are sold separately.

Key Features

• 5/8-in. brush head sized for 5/8-in. hole diameter - matches the correct hole geometry for a thorough, wall-to-wall clean on every stroke, reducing debris left behind.
• Compatible with #4 rebar size - takes the guesswork out of brush selection by confirming a direct match to the anchor rod size being installed.
• Approved for use with Simpson SET-3G and AT-3G adhesives - ensures the brush meets the adhesive manufacturer's hole-prep requirements, supporting a properly bonded anchor.
• Achieves proper cleaning with fewer brush strokes at embedments up to 20 times the anchor diameter - saves time on the job while still meeting the hole-prep standard required for high-strength adhesive anchoring.
• 5-in. useable brush length with modular system compatibility - pairs with the separately available T-handle and optional extensions so total usable length can be configured to match actual embedment depth.

Why This Product

• Purpose-built for adhesive anchor prep - this brush head is designed specifically for cleaning drilled holes before adhesive anchor installation, not a generic option, meaning it is sized and constructed to meet the hole-cleaning standards that SET-3G and AT-3G adhesive systems require.
• Fewer strokes, faster prep - the brush is engineered to permit proper hole cleaning with fewer brush strokes, reducing labor time on repetitive anchor installations without compromising cleanliness.
• Scalable to deep embedment work - with support for embedments up to 20 times the anchor diameter and compatibility with optional extensions, this brush head adapts to shallow and deep anchor applications alike without requiring a different tool.
• Exact-fit sizing eliminates guesswork - the 5/8-in. brush head is matched to a specific hole diameter and rebar size, so contractors can confidently select the right brush for the anchor being installed and move on without second-guessing compatibility.
