Steel Stud Anchors for Concrete

Also known as wedge anchors, the base expands as you tighten the nut for a secure hold in concrete. They're often used to anchor machinery. Pull-out strength and shear strength values are 25% of the ultimate values.

Zinc-plated and zinc yellow-chromate plated steel anchors are corrosion resistant in wet environments.

Galvanized steel anchors are more corrosion resistant than zinc-plated steel anchors. They must be used with other galvanized fasteners.

ICC listed anchors are often required for new construction. Anchors listed for cracked concrete are often required in environments which may cause concrete to crack during the life of the anchor.

Super-Corrosion-Resistant 316 Stainless Steel Stud Anchors for Concrete

More corrosion resistant than 18-8 stainless steel anchors, these 316 stainless steel anchors have excellent resistance to chemicals and salt water and may be mildly magnetic. Also known as wedge anchors, the base expands as you tighten the nut for a secure hold in concrete. They're often used to anchor machinery. Pull-out strength and shear strength values are 25% of the ultimate values.

18-8 Stainless Steel Stud Anchors for Concrete

These 18-8 stainless steel anchors have good chemical resistance and may be mildly magnetic. Also known as wedge anchors, the base expands as you tighten the nut for a secure hold in concrete. They're often used to anchor machinery. Pull-out strength and shear strength values are 25% of the ultimate values.

ICC listed anchors are often required for new construction. Anchors listed for cracked concrete are often required in environments which may cause concrete to crack during the life of the anchor.

Vibration-Resistant Stud Anchors for Concrete

Keep fixtures solidly in place—these anchors have two locking wedges that won't shake loose. Also known as wedge anchors, the base expands as you tighten the nut for a secure hold in concrete. They're often used to anchor machinery. Made from zinc-plated steel, they resist corrosion in wet environments. Pull-out strength and shear strength values are 25% of the ultimate values.
