High-Torque Fastening Systems
Since 1940, Century Drill & Tool has supplied high-durability hand tools to industrial distributors, commercial suppliers, and automotive aftermarket networks. Our fastening tools utilize premium Chrome Vanadium (CR-V) and heat-treated S2 alloy steel to prevent cam-out, distortion, and fatigue under continuous heavy-duty service.
13 Piece SAE/Metric Hex Key Wrench Set
Heat-treated alloy steel construction with precision chamfered ends for smooth insertion into hex socket fasteners without rounding.
13 Piece Professional Screwdriver Set
S2 steel blades hardened for maximum torque transmission. Features ergonomic tri-lobe anti-slip grips and magnetic vapor-blasted tips.
5 Piece Hollow-Shaft Nut Driver Set
Full-hollow shafts facilitate working on long bolt applications and stacked nuts. Precision socket geometry prevents corner stripping.
5 Piece Drop-Forged Open End Wrench Set
Drop-forged steel with 15-degree angled heads for enhanced levering in restricted engine bays and mechanical tight spaces.
Industrial 6-in-1 Multi-Bit Screwdriver
Combines two double-ended steel bits with two nut driver sizes inside a high-impact resin handle. Ideal for field service technicians.
7 Piece Compact Folding Hex Key Set
Housed in a reinforced ABS composite body. Keys lock into place at 90° and 180° positions for maximum leverage in compact field kits.
9 Piece Long Arm Ball End L-Wrench Set
Ball-end design allows up to a 25-degree entry angle to reach off-axis socket screws in crowded electrical or mechanical assemblies.
Precision Machined Adjustable Wrench
Non-protruding jaw knurl mechanism ensures zero backlash during operation. Precision laser-etched scale in both Metric and SAE units.
Heavy-Duty Forged Steel C-Clamp
Designed for heavy fabrication, welding, and woodworking. Features anvil-flat pressure surfaces and copper-plated anti-spatter spindles.

Frequently Asked Questions
Our professional screwdrivers, hex keys, and bit drivers are manufactured using high-grade S2 modified tool steel and heat-treated Chrome Vanadium (CR-V 6150) steel. Shafts are hardened to HRC 54–62 to eliminate distortion and round-off during high-torque applications.
Yes. All Century Drill & Tool hand tools strictly adhere to ANSI (American National Standards Institute), DIN (German Institute for Standardization), and ISO specifications for dimensional tolerances, torque strength limits, and plating thickness.
We offer full packaging customization, including retail clamshells, molded index cases, counter display units, hanging blister cards, and bulk industrial packaging. All items can be pre-printed with your company's branding and barcode standards.
Ball-end hex wrenches feature a spherical tip profile allowing the user to insert the key into fastener sockets at up to a 25-degree angle. This is essential for turning socket screws located in recessed, obstructed, or hard-to-reach locations.
