Hex Head Security Bits
We take an S2 material T30 Torx bit as an example. The hardness is HRC 58-62. The minimum break torque is ≥30 N·m. This follows ISO 1173. In real use, you can safely put out 20-25 N·m of torque. This meets the needs of M8 Torx screws. Under repeated tightening and loosening at 20 N·m torque, an S2 bit can handle 5000 cycles.
Change Bits Fast with Our Hex Head Security Bits
Do you use a power drill or an electric screwdriver? You need to change bits quickly. Our Hex Head Security Bits have a standard 1/4 inch (6.35 mm) hex shank. You can change them fast. We are a Shanghai factory. We have supplied fasteners for 20 years.
Check Our Torque Data and Cycle Life
We take an S2 material T30 Torx bit as an example. The hardness is HRC 58-62. The minimum break torque is ≥30 N·m. This follows ISO 1173. In real use, you can safely put out 20-25 N·m of torque. This meets the needs of M8 Torx screws. Under repeated tightening and loosening at 20 N·m torque, an S2 bit can handle 5000 cycles. It shows no big wear. A 45# steel bit handles about 2000 cycles. Our size range: Torx T15, T20, T25, T30, T40. These fit M4 to M8 Torx combination screws. Hex H2, H2.5, H3, H4, H5, H6, H8. These fit M2 to M10 internal hex bolts. We offer 45# steel and S2 alloy steel. 45# steel has hardness HRC 48-52. It is an economic choice for normal assembly. S2 alloy steel has hardness HRC 58-62. It is a pro choice for high strength or high frequency use. The production uses precision cold forging or CNC grinding. The drive end shape meets ISO 10664 (Torx) or ISO 2936 (hex). The 1/4 inch hex shank meets DIN 3126. It works with most quick change chucks.

Why Our Coating and Length Options Matter
Surface finish is nickel plating or black oxide. Nickel plating thickness is 5-8 μm. The surface is bright and hard (HV 400-500). It resists wear well. Salt spray test lasts 48 hours with no rust. A Torx bit touches the screw on the face, not at a point. The risk of tool slip is 80% lower. This protects the screw slot. Length options: standard short bit 25 mm for pistol grip drills. Long bits 50 mm, 75 mm, 100 mm for tight or deep holes. Double end bits have Torx on one end and hex on the other. Or two different sizes. We can add a magnetic tip. It holds the screw and stops drops. This speeds up assembly. Mass production takes 2-3 weeks for standard parts. Custom products take 4 weeks. Payment is 30% deposit and 70% balance. We take US dollars. We pack your order well. We have done this for 20 years.
The entire product line is fully customizable.
