Non-Standard Fasteners

Verity of Standard Products

Custom Designed Fasteners For Cement And Mining Industries

We manufacturers a wide range of mill liner bolts for use in the milling process which are designed to withstand extreme rotational, impact and crushing forces in ball mill and SAG mill.

Specialty of Mill liner Bolts: –

Precision Forged Design

Bolts ensure a flush fit with the liner plate to eliminate movement and maximize load transfer during grinding operation.

Ultra-High strength

Bolts are Manufacture to withstand extreme rotational and impact loads. Tensile strength typically exceeds 1000 Mpa, depending upon material and application

Advanced Heat treatment

Bolts undergo Hardening, quenching and tempering to achieve a tough core and hardened surface ensuring resistance to Fatigue, wear and deformation under cyclic load.

Superior Thread integrity

Threads are formed by Roll threading which offers high resistance to stripping and thread fatigue under repeated tightening cycles

Anti-vibration Locking

Bolts equipped with Hardened Heavy duty cup washers and self-locking Nuts to maintain tension and prevent loosening under dynamic load and vibrations

Corrosion & Abrasion Resistance

Bolts supplied with black oxide, Zinc plating, galvanizing or fluoropolymer coating as per customers requirement to protect against slurry, dust and moisture in aggressive mill atmosphere

Material grade

Built strong from carbon steel, alloy steel and stainless steel , we customize our bolts as per customers design to meet specific requirements.

Most common material grade

SAE 4140/42crMo4/EN19- For High strength & toughness Property class 8.8,10.9 as per ISO 898- 1 & ASTM A 193 grade B7 for standard heavy-duty application

Our machining, heat treatment and technical capabilities complement the forge operation to deliver technical products of the highest integrity.

All head shapes, lengths and diameters of forged products are catered for and customized for any requirement. Specific design, tension and optimal head seating are critical components to reduce mill shut down risk
