Parts photographed on our own shop floor at Focal Point, Ludhiana — not catalogue images. Every piece shown here was made to a customer drawing or to the standard called up on the order.

Foundation and Anchor Bolt Assemblies

Welded plate assemblies built complete in-house: base plate, triangular stiffener gussets, pipe sleeve and tuck nut where the drawing calls for one. Manufactured up to 110 mm diameter, and in quantity up to 3750 mm long.

Anchor bolt assembly showing full length, rolled thread and welded gusset plate at the embedded end — **Anchor bolt assembly** Full length, rolled thread one end, welded plate with gussets at the embedded end. Weight calculator →

Welded plate foundation bolt assemblies with base plate, triangular stiffener gussets and heavy hex nuts fitted — **Welded plate assemblies** Base plate with triangular stiffener gussets, nuts fitted at the threaded end. Weight calculator →

Close view of triangular stiffener gussets welded between rod and base plate on foundation bolt assemblies — **Stiffener gusset detail** Gussets carry the load path from rod into plate so the weld is not working in bending alone.

Foundation bolt assemblies in red oxide primer with pipe sleeve welded below the threaded section — **Pipe sleeve assemblies** Sleeve welded below the thread leaves the upper section free to flex for setting out on site.

Pipe sleeve and gusset detail on welded plate anchor bolt assemblies, red oxide primed — **Sleeve and gusset detail** Pipe called up by nominal bore and class on the drawing, cut here by outside diameter and wall thickness.

110 mm diameter foundation bolts wrapped and packed with nuts fitted, ready for dispatch — **110 mm foundation bolts** Wrapped and packed with nuts fitted. The largest diameter we manufacture.

J and L Type Foundation Bolts

Bent anchors are formed first and heat treated afterwards, so the bend is never made in hardened material. Supplied in property classes 8.8 and 10.9 as well as mild steel.

J type foundation bolts with rolled threads and black finish, manufactured at S R Forgings Ludhiana — **J type foundation bolts** Threaded one end, curved hook the other. Hook radius controlled to avoid damage at the bend.

L type foundation bolts with 90 degree bend and rolled thread, laid out on the shop floor — **L type foundation bolts** Square 90° leg instead of a curved hook, where reinforcement clearance decides the shape.

J type foundation bolts loaded on a vehicle for dispatch from S R Forgings — **Loaded for dispatch** A completed J bolt order going out from Focal Point, Ludhiana.

Special and Made-to-Drawing Anchor Bolts

Where a drawing calls for something outside the standard range, we make to the drawing. These are parts built for a specific specification rather than a catalogue item.

Special anchor bolts with shallow drilled keying pockets along the shank for concrete bond, road over bridge project — **Anchor bolts with drilled keying** Shallow blind pockets, 5 mm deep, along the embedded length so the concrete keys to the rod instead of relying on a smooth bar. Made for a road over bridge foundation.

Eye end anchor rods with forged loop and rolled thread, red oxide primed — **Eye end anchor rods** Forged loop at the embedded end so a bar can be passed through and tied into the reinforcement cage.

Rolled thread run out detail on anchor bolts showing transition from shank to thread — **Rolled thread detail** Threads rolled rather than cut, so the grain follows the thread form instead of being severed. Torque calculator →

Machined Bolts and Drift Pins

Turned on PLC-controlled machines from 20 mm to 75 mm diameter, in property classes 8.8, 10.9 and 12.9. Machining is used where the size, the head form or the shank tolerance puts a part outside what can be forged from stock tooling. We machine both before and after heat treatment. Turning after heat treatment is slower and harder on tooling, and we do it where a customer wants it: it leaves a bright, clean surface, so the bolt goes to site looking like the finished article rather than a scaled forging.

Large diameter CNC machined hex bolts standing in bulk at S R Forgings, Ludhiana — **Machined bolts, bulk lot** Turned from bar, 20 mm to 75 mm diameter, threads rolled. One order, photographed here and in the two frames alongside. Weight calculator →

Machined hex bolts with plain shank and rolled thread, close view — **Plain shank detail** The same bolts close up: shank left parallel at nominal diameter where the drawing calls for a fitted shank.

Machined high tensile bolts in black finish with nuts assembled — **Assembled and packed** Black finish with nuts fitted, ready for inspection and dispatch.

Tapered barrel drift pins manufactured by S R Forgings, Ludhiana — **Drift pins** 20 mm to 36 mm diameter, turned to a true continuous taper so they drive and withdraw cleanly. Drift pins →

Drift pin tapered end detail held in hand for scale — **Taper and point** Long even taper with a blunt point, so the pin draws misaligned plies together rather than wedging. Drift pins →

Steel erection drift pins in machined finish — **Erection drift pins** Used on girder splices, towers and pre-engineered building steelwork to bring bolt holes true.

Shear Connector Studs and PSR Studs

Headed shear connector studs to ISO 13918, and custom studs to drawing, from 13 mm to 1¼ in. diameter and up to 40 in. long, supplied with matched ceramic ferrules. PSR punching shear studs for the column zones of flat slabs. Shear stud production capacity is 150 tonnes a month.

Headed shear connector studs in black finish with SRF marked on the heads, manufactured by S R Forgings, Ludhiana — **Headed shear connector studs** A production lot, with the SRF mark on every head. Shear connector studs →

PSR punching shear resistor studs with long shanks and large flat heads, manufactured by S R Forgings — **PSR studs** Punching shear resistor studs: long shank, large head, used in rows around columns in flat slabs. Shear studs vs PSR studs →

PSR punching shear studs with ringed heads stamped SRF, S R Forgings Ludhiana — **PSR stud heads** Large heads with concentric rings and the SRF mark, one piece with the shank. Shear stud capacity →

Nuts, Washers and Finishes

Fasteners are supplied as complete sets wherever the connection needs one, with the nut, washers and coating matched to the bolt rather than sourced separately.

One piece forged dome nuts, zinc plated, manufactured by S R Forgings — **Dome nuts** One-piece forged, M16 to M36 — no pressed cap to work loose in service. Nuts →

Double coil spring washer in heat treated spring steel, hot dip galvanised — **Double coil spring washer** Heat treated spring steel, hot dip galvanised, 5/8" to 1". Supplied with the matching bolt and nut. Washers →

Hot dip galvanised bolt, nut and washer sets — **Galvanised sets** Nuts tapped oversize after galvanising and supplied matched to their bolts, lot for lot. Coatings →

Zinc flake coated high tensile bolts — **Zinc flake coating** No hydrogen charging of the steel, so it suits property class 10.9 and 12.9 where plating cannot be used. Coatings →

Manufactured to your drawing

Everything on this page was made at E-615, Phase-VII, Focal Point, Ludhiana. Foundation and anchor bolts are manufactured up to 110 mm diameter, and in quantity up to 3750 mm long, in mild steel and in property classes 8.8 and 10.9. Assemblies are supplied complete with matched nuts and washers, in self colour, red oxide primer, black or hot dip galvanised finish.
