(types of wall bolts)
Wall bolts serve as critical components in modern construction, with 82% of commercial projects requiring specialized anchors for concrete or masonry surfaces. The primary variants include:
Recent ASTM E488 tests show modern polymer-coated wall screw anchor types increase corrosion resistance by 70% compared to untreated steel models.
Type | Material | Shear Strength | Tensile Strength | Temperature Range |
---|---|---|---|---|
Wedge Anchors | Zinc-Plated Steel | 24kN | 32kN | -40°C to 150°C |
Toggle Bolts | Stainless 316 | 18kN | 25kN | -60°C to 260°C |

Current prototypes of long wall anchor bolts demonstrate 40% faster disengagement for maintenance access compared to 2020 models.
(types of wall bolts)
A: Common heavy-duty wall bolts include sleeve anchors, wedge anchors, and toggle bolts. These provide strong support for hanging heavy objects on concrete or masonry walls. Always choose based on wall material and weight requirements.
A: Drywall anchors (e.g., plastic expansion or molly bolts) spread pressure behind hollow walls. Concrete anchors (e.g., wedge or sleeve anchors) use friction or expansion in solid materials. Material strength dictates the anchor type required.
A: Long wall anchor bolts are ideal for thick masonry walls or layered materials requiring deep penetration. They ensure stability in uneven surfaces or when anchoring through insulation/weather barriers. Use them for structural connections in load-bearing scenarios.
A: Plastic anchors suit lightweight items in drywall or plaster. Metal anchors (steel/zinc) handle heavier loads in concrete or masonry. Metal variants often feature expandable sleeves for increased grip strength.
A: Most expansion-type anchors (e.g., sleeve anchors) are single-use due to deformation during installation. Toggle bolts or friction-based anchors can sometimes be removed and reused. Always check manufacturer guidelines for specific bolt types.
