Hook wrenches: also known as crescent wrenches,it is used to turn flat nuts with a limited thickness, etc .; special for round nuts on vehicles,machinery and equipment,card slots are divided into rectangular card slots and round card slots.

The material is beryllium copper or aluminum copper alloy,so that can effectively avoid sparks during work.Non sparking tools are suitable for all flammable and explosive places.

Non sparking hook spanner

Non sparking tools should have a proper maintenance phase after they are used in our daily work.it's critical to the life of the tools.If the products can not be properly maintained,the tools will not service us long.First of all,we should keep the hand tools in the dry place,that can not damage our product parts.

Explosion proof tools keep our staff who worked in flammable,explosive and easy to corrosion place safe,so that our staff rest assured.

In our daily work,after 20 consecutinve strokes,we must treat the surface attachment of the copper hand tool and wipe it clean before using it,never using continuously.Prelonged friction can heat our products and damage our tools.

Copper hand tools

The material of non sparking tools: Al-Br(QAl11-4-4), Be-Cu(QBe2)

Be-Cu: the color is green lake,hardness is not less than HRC35,tensile strength δ b 105-120kgf/mm2;standard code GBEX ⅡC,suitable for hydrogen with concentration 21.0±2.0%.Beryllium copper alloy with anti-magnetic performance.

Al-Cu: the color is bluish yellow,hardness is not less than HRC25,tensile strength δ b 75-85/mm2;standard code GBEX ⅡB,suitable for ethylene with concentration 7.8±0.5%,GBEX ⅡA (propane 6.5±0.5%),Ⅰ（methane 6.5±0.5%）。

Non sparking tools of XIN DA are made of high strength copper alloy.This kind hand tools can effectively prevent burning and explosion accidents caused by friction and collision between tools and tools in the flammable and explosive workplace.The explosion-proof performance received the certificates according to the national standard GB10686-2003, with the function of high intensity and good toughness.

The products are widely used in petroleum,chemical industry,mining,gas,coal,oxygen-producing,pharmacy,smelting,powder,leather,airplane,marine engineering etc,suitable for warehouse that operate flammable and explosive products,electrolytic workshops,communication assembly workshops,and requires that the tools are not rusty,wear-resistant and anti-magnetic during the checking process.
