Why Uniloc Fasteners

Why you should insist only on UNILOC FASTENERS products out of all conventional hot forged sockets head cap screws hex head bolts?

Because of

• Reliability
• Fatigue resistance
• Higher Strength
• Cost of fixing reduces
• Reduces the assembly size
• Reduces No. of fasteners and/or reduces dias

Hot forged SHCS/HH products have many specialities compared to conventional products like

• RM special preparation
• Heating of the material
• Formation of the head
• Control of depth of socket
• Annealing and shot blasting
• Thread formation
• Filet Shape
• Heat treatment
• Antirust Grey phosphating

Raw Material preparation - Special and unique

• We buy high quality alloy steel black bars directly from reputed steel manufacturers with certificates
• They are annealed to give better structure
• They are drawn to size on draw benches to make straight
• Bar are peeled minimum 2mm thickness to remove all surface defects
• After peeling they are reeled and then ground to correct size of body dia of fasteners

Advantages of Raw Material Preparation

• Surface cracks are removed completely, if any
• Raw materials conditioned by annealing processing
• Products heads are forged directly from body dia bars
• This ensure material fiber/grain are not cut

Heating of Materials

• Raw materials is heated by resistance CNC controlled heater/Induction heater
• Raw materials heated only to the desired length for forging
• This will not change total structure of the material

Head Formaing

• Heads are formed by using carbide dies to give correct dimensions
• Head forming operations done in two strokes in the same setting die by using sliding tool technology-one die two blow
• In this process we ensure that heads are accurate and concentric with respect to the body
