Brass Anchors (Rawl Bolts)
Bharti Enterprise manufactures knurled brass expansion anchors and Rawl bolts for construction and industrial fixing — precision-turned fasteners that expand against the drilled hole to give a secure, corrosion-proof hold in concrete, stone and masonry.
Engineered, not just supplied.
Machined from free-cutting brass on the same CNC and traub lines as the rest of the fastener range, anchors are produced in standard metric sizes and custom designs to drawing, with the knurling depth and expansion geometry that determine holding power controlled to tight tolerances.

Brass Anchors (Rawl Bolts) — answered.
The questions engineers and buyers ask us most. Something missing? Ask us directly — a specification answer costs nothing.
01What are brass anchors (Rawl bolts) used for?
Brass expansion anchors secure fixtures into concrete, stone and masonry — the knurled brass body expands against the drilled hole as the screw drives in, giving a firm, permanent hold for sanitary ware, electrical fittings and fixtures.
02Why choose brass anchors over steel anchors?
Brass doesn't rust in damp masonry or wet areas, is non-sparking and non-magnetic, and machines to precise expansion geometry — so holding power stays consistent for the life of the fixing.
03What sizes of brass anchors are available?
Standard metric sizes with custom designs to drawing — knurling depth and expansion geometry are machined to tight tolerances on CNC lines in Jamnagar, India.
04Can anchors be customized for a specific application?
Yes — Bharti Enterprise manufactures custom anchor designs from drawings or samples, matching thread, length and expansion behaviour to your fixing requirement.
05Are the anchors export-quality?
Yes — produced under ISO 9001:2015 and IATF 16949:2016 quality systems and exported with the wider fastener range to 50+ countries including the USA, UK, Germany and UAE.
06What finishes are available on brass anchors?
Natural brass, nickel and tin plating — chosen for the installation environment and appearance requirements.
