More info
This description covers the NIETZ 53253 series Extra-Long Ball Point Hex Wrenches (Black Finish) across all listed metric sizes, from 1.5mm to 10.0mm.
Product Overview
The NIETZ 53253 series consists of professional-grade L-shaped hex keys designed for high-torque fastening and loosening of hexagonal socket screws. This specific "BK" (Black) series is characterized by its extra-long arm design, which provides increased leverage and superior reach into deep or obstructed areas compared to standard-length wrenches.
Key Features
-
High-Performance Material: Manufactured from S2 Alloy Steel, a premium tool steel known for its extreme toughness and resistance to breakage compared to standard Chrome Vanadium (Cr-V).
-
Advanced Heat Treatment: Subjected to a specialized 3S heat treatment and tempering process, achieving a hardness of HRC 58º ± 2 for maximum durability and tool life.
-
Ball Point End Design: Features a spherical ball point on the long arm, allowing the wrench to engage fasteners at a working angle of up to 25°—perfect for tight spots where a straight entry is impossible.
-
Industrial Black Finish: The "BK" designation refers to a protective black oxide or phosphated finish that provides enhanced corrosion resistance and a non-slip surface.
-
Precision Machined: Precision-cut ends ensure a snug fit into screw heads, significantly reducing the risk of rounding out the fastener or stripping the tool.
