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
