India's largest range of toggle clamps — vertical, horizontal, push-pull, pull action & squeeze. 800+ models, 45 kg to 4,500 kg holding capacity. Zinc-plated steel and SS 304 variants.
Downward clamping with minimum 90° opening angle. Seven sub-series including Front Mounting, Heavy Duty, and TRIG anti-vibration variants. Capacities from 100 kg to 9,800 N.
VTC clamps use an over-centre toggle mechanism that locks solidly in the closed position with zero back-drive. The self-locking geometry means no external latch is needed under normal vertical loads.

VTC Series clamps are the most widely deployed toggle clamp type in manufacturing fixtures due to their versatility and positive-locking geometry.
VTC-UB series holds sheet metal and weldments securely without marring surfaces. TRIG variant resists vibration from MIG/TIG arcs.
SF series with fixed guide bush ensures repeatable spindle positioning for high-volume assembly.
Precise, repeatable clamping force for dimensional checking without distorting thin-walled parts.
UB adjustable series accommodates varying timber thickness in joinery and cabinet-making jigs.
HV heavy-duty series for body-panel pressing, hemming dies, and structural weld fixtures up to 9.8 kN.
Miniature VTC series for PCB soldering and test fixtures requiring low actuation force.
Low-height profile clamps where handle and bar move in opposite directions. Four sub-series from miniature (50 kg) to medium-heavy (1,000 kg). Ideal for low-clearance fixture designs.
The horizontal hold-down clamp's low-profile geometry makes it the first choice when vertical clearance above the fixture is restricted. The opposing handle-bar motion provides a mechanical advantage that translates to high clamping force from a compact package.

H-Series clamps are chosen when fixture height is critical — assembly pallet lines, transfer machines, and robot-loaded jigs where parts must enter from the top without obstruction.
Low profile keeps parts clear of transfer rails and automation tooling paths.
Minimal protrusion above fixture surface allows safe robot arm approach.
Horizontal handle swing keeps operator hands away from weld zone.
Medium-duty H-225/235 series for repetitive manual assembly operations.
Widest capacity range in the Steel-Smith lineup — from 45 kg miniature to 4,500 kg heavy-duty. Lockable in two positions. Eight sub-series including Low Height, Flat Handle, Front Mount, and Package Size.
The straight-line action means the plunger force vector is coaxial with the plunger axis — ideal for push or pull clamping without side-loading the spindle. Dual lock positions allow use as either a push or pull clamp on the same fixture.

HTC push-pull clamps excel where workpieces must be pushed into a datum stop or pulled against a locating face — particularly in drilling, machining, and automated assembly.
Miniature HTC-601 provides precise, repeatable hold on printed circuit boards during soldering.
Standard HTC flanged series on router and CNC tables for panel clamping.
Pull-type HTC holds parts against weld backing bars; dual-lock prevents movement from arc vibration.
HTC-SS 304 variants meet hygiene requirements for tablet press and filling machine tooling.
SS 304 electro-polished variants for clamp-down covers and guards on food-grade machinery.
HTC-FM front-mount for edge-mounting on milling and drilling jig bodies.
Designed for sealing chambers, mould closures, access doors, and lid applications. Threaded U-bolt provides height adjustment. MS and SS 304 variants with multiple U-bolt extension lengths.
The pull action clamp uses a U-bolt bar hook that engages a latch or keeper mounted on the opposing face. Pulling the handle down over-centres the mechanism, creating a powerful compressive seal force. The threaded U-bolt allows fine height adjustment without fixture modification.

PAH pull action clamps are the go-to solution for pressure vessel lids, inspection hatches, oven doors, and any application requiring a reliable latch under sustained load.
Provides a secure, one-hand latch for inspection doors on machinery enclosures.
Mould closures, vacuum chambers, and pressure vessel lids with adjustable sealing force.
SS 304 electro-polished PAH-SS series for hygienic lid and cover applications.
Cleanroom-compatible SS variants for blender lids, isolator doors, and autoclave closures.

Forged heat-treated alloy steel jaws machined to close tolerances. 60 mm wide jaw for full surface contact. No fixture mounting — fully portable. Ideal for sheet metal bending, forming, and crimping.
The TP squeeze clamp is the portable workhorse of the Steel-Smith range. Forged from heat-treated alloy steel for maximum toughness, it locks mechanically when both handles reach the central (over-centre) position, holding the workpiece without operator effort.

| Portability | Fully portable; no fixture mounting required |
| Jaw Opening | Multiple sizes available (model-dependent) |
| Finish | Zinc Plated (standard) |
| Primary Applications | Sheet metal bending, forming, crimping, portable clamping, welding |
The TP series is essential in sheet metal shops, fabrication yards, and maintenance workshops where mounting a fixture clamp is impractical.
Holds sheet metal workpieces firmly at brake press or during hand forming operations.
Portable grip for tack-welding assemblies before moving to a fixture for final welding.
Jaw geometry distributes force evenly during crimping of edges, brackets, and hems.
On-site clamping without access to dedicated fixtures; quick set-up and release.
Solid arm (SF) for flat surfaces with fixed height. U-bar adjustable (UB) for irregular or variable-height parts. Fixed-hole arm for simple downward clamping.
Select model with X1 capacity ≥ required clamping force. Use X2 (sustained load) for continuous-duty applications. Add 20–30% safety margin for dynamic loading.
Low-height: H-Series or HTC-LH. Edge-mounting: HTC-FM or VTC-FM Front Mount. Overhead/inverted: TRIG variant mandatory to prevent gravity release.
Wet or corrosive environments: SS 304 Electro Polished. Food & pharma: SS 304 with Electro Polish. Standard industrial: Zinc Plated MS. Temperature –20°C to +150°C.
High-cycle applications (>500 ops/day): choose forged heavy-duty models with precision pivot pins. Evaluate spindle wear rate for long-run production jigs.
TRIG series locks the arm in both open and closed positions. Essential for overhead mounting, vibratory conveyors, and fixtures on machine tools during cutting.
PAH Pull Action series for lid, hatch, and mould closure requirements. Multiple U-bolt extension lengths allow height adjustment post-installation.
Steel-Smith's dedicated Pneumatic Clamp range (separate product line) is recommended for automated high-cycle operations where manual actuation is not feasible.
Our Pune team can help you select the right series, arm type, capacity, and material for your specific welding, assembly, or machining application. SS 304 and custom configurations available.
