Car Wheel Lug Wrench and Emergency Tool Kit

-- Steady & Reliable Manufacturer --

Introduction

Car wheel lug wrenches and emergency tool kits are the tools carried in a vehicle for changing a tire or doing roadside repairs. A typical kit combines a wheel lug wrench, spanners, a screwdriver and a scissor car jack with its screw rod. Wrenches are made in common socket sizes such as 17, 19, 21 and 22 mm to suit different wheel nuts and bolts.

Shanghai Soverchannel Industrial Co., Ltd. produces on-board tool kit parts at its Nantong Jinzhai Hardware plant, together with jack screw rods and fasteners, so a kit can be supplied from one source with branding and packing to the buyer specification.

Replacement bolts for pumps, conveyors and crushers, ordered by standard number and class.

Steel Framing

Brackets, base plates and light structural connections.

Automotive Chassis

Cross-members, subframe brackets and suspension mounts where class 8.8 is specified.

Agricultural Machinery

Core Features

  1. Hex head: standard wrench sizes allow fast tightening with common tools.
  2. Quenched and tempered core: delivers the 800 MPa tensile level required for class 8.8.
  3. Rolled thread: improves fatigue performance compared with cut threads.
  4. Gauge-checked threads: go and no-go gauges confirm fit before packing.

Frequently Asked Questions

What is the difference between DIN 933 and DIN 931?
DIN 933 is fully threaded, while DIN 931 has a plain shank section. Use DIN 933 for short grips or tapped holes, and DIN 931 when the unthreaded shank should carry shear load.
Is DIN 933 the same as ISO 4017?
Dimensions are very close and the two are used interchangeably in most orders. State both numbers on the purchase order and the drawing to avoid confusion at inspection.
Can I get class 8.8 bolts with a hot-dip galvanized finish?
Yes. Class 8.8 is generally accepted for hot-dip galvanizing. Nuts must then be tapped oversize so the thread still assembles.
What documents can be supplied with an order?
Material certificates, mechanical test reports and coating thickness records can be provided for each batch when requested at the quotation stage.
