## Summary description

Tvardy Impact screwdriver bit H4, 25 mm length, manufactured from S2 tool steel. Available in pack counts of 2, 10, 50 and 500 pieces.

## Long description

Tvardy Impact screwdriver bit H4, 25 mm, is a compact driver bit designed for use with impact drivers and screwdrivers. Manufactured from S2 tool steel, this bit offers increased toughness and resistance to shock loads common when fastening H4-type fasteners. Available in multiple pack sizes, it fits standard 1/4" hex chucks and is intended for both professional tradespeople and DIY users who need reliable, repeatable performance when driving H4 screws.
Advantages
The S2 tool steel construction provides enhanced durability and better resistance to wear compared with standard steel bits. The 25 mm length gives a balance between reach and control, reducing wobble during high-torque impact driving. Designed specifically for H4 fasteners, the bit head geometry ensures accurate engagement and helps prevent cam-out. Multiple pack size options allow purchasing to match job scale, from occasional home use to bulk needs for workshops or construction sites.
Suitable for
 Driving H4 screws with impact drivers and cordless screwdrivers
 Professional installation and assembly tasks requiring shock-resistant bits
 DIY projects where durable, repeatable fastening is needed
 Workshops, construction sites, and maintenance operations
Key specifications
 Bit type: H4 screwdriver bit
 Material: S2 tool steel
 Length: 25 mm
 Drive connection: 1/4" hex-compatible
 Intended use: impact-rated (impact driver and impact screwdriver compatible)
 Available pack quantities: small to bulk packs to suit different needs
How to use
Insert the H4 bit into the 1/4" hex chuck of your impact driver or screwdriver until it seats securely. Select appropriate torque and speed settings for the fastener material and size. Apply steady pressure and allow the impact tool to drive the screw, keeping the bit aligned with the fastener to ensure correct engagement. After use, inspect the bit tip for wear or deformation and replace when engagement becomes inconsistent.
Usage recommendations
For longer bit life, avoid excessive side loading and use torque settings suitable for the fastener and substrate. Store bits in a dry place and consider swapping to fresh bits if frequent cam-out or rounding of the fastener head is observed.
