Hex Bolts & Special Fasteners Manufacturer in Pune
Precision-machined and special-purpose bolts and fasteners manufactured to customer drawings and specifications. Santosh Engineering Works manufactures studs and special fasteners completely in-house — from raw bar through CNC turning, thread forming, chamfering and inspection. Parts are made to your drawing: thread form, pitch, length, grade, collar or dog-point details and any special feature your assembly needs. Being a drawing-based manufacturer rather than a stockist means you get non-standard sizes and special features without compromise, in batch quantities that suit OEM and Tier-1 production schedules.
