Product Catalogue

Every fastener your build needs —
and the ones it can't find anywhere else.

A full catalogue of bolts, screws, studs, nuts and washers — plus the non-standard parts most suppliers turn away. Made in property classes 8.8, 10.9 and 12.9 to whatever standard governs your order — DIN, IS, JIS, BS or ASME — or purely to your drawing. We cross-map the standard so the part drops straight into your assembly.

ASME B18.2.2

Hex, flange and special nuts in MS, Grade 8 and Grade 10 — formed in-house up to A/F M50×4 so the complete joint ships from one source.

Washers

Plain & SpecialDIN 125 · ISO 7089 · IS 2016

Plain, spring and special washers matched to every bolt and nut we supply — one accountable source for the whole joint.

DIN references shown with their nearest ISO, IS (Indian), JIS (Japanese) and ASME/ASTM (imperial) equivalents. Cross-standards match in form and function but differ in fine detail — every KFP order is manufactured and inspected to the single standard or drawing that governs your purchase order.

About Kapur Fasteners

Two generations.
One standard.

The Kapur family's journey in fasteners began in 1983 — more than four decades of forging, learning and earning trust under an earlier banner. In 2005, Mr. Rajesh Kapur channelled that legacy into Kapur Fasteners Private Limited: a new name carrying twenty-two years of accumulated craft, and an outsized commitment to customer satisfaction.

Today, under second-generation leadership, KFP operates two manufacturing units in Ballabgarh, Faridabad — the fastener heartland of North India — serving automotive, OEM and industrial supply chains with both standard hardware and the non-standard, made-to-drawing parts that built our reputation.

Our promise has never changed: timely delivery of products whose performance and appearance honour a tradition of high manufacturing standards.

Rajesh KapurFounder & Managing Director

In the fastener trade since 1983. Built KFP on four decades of hands-on craft and honest commitment to every customer.

Karran KapurChief Executive Officer

Second-generation leadership driving operations, quality systems and KFP's growth into new markets.
