Introduction
A hand tools manufacturer from Delhi has recently lost a significant industrial order valued in lakhs since their Open Jaw Wrenches did not have the BIS certification under IS 2028:2004. The buyer wanted all wrenches to carry the ISI mark, confirming compliance to national safety and performance standards.
This is a frequent circumstance experienced by hand tool manufacturers in India. Many did not know BIS certification is mandatory under Indian law and that IS 2028:2004 outlines material quality, dimensional accuracy and mechanical performance. Certification provides assurance regarding the safety, reliability and marketability of a given
What is IS 2028:2004?
IS 2028:2004 is the Indian standard for Open Jaw Wrenches, as indicated by the Bureau of Indian Standards (BIS), to specify the material, would be dimensional, mechanical and performance criteria for an acceptable quality of wrench.
Some of the main points of IS 2028:2004 are:
- Material Specifications: Maintain list of acceptable steel grades, hardness requirements and surface treatment for corrosion resistance.
- Design and Dimensions: Determines the width, thickness, and length of the jaws on the wrench and gives tolerances to provide a proper fit.
- Mechanical Performance: Tests for wrench performance under specific torque, determines mechanical limits of jaw stretching, and measures the wrench’s resistance to distortion.
- Durability and Safety: Tests for repeated use performance, ensuring the wrench is capable for use in the performance zone, determining lung capacity and avoiding cunning and symmetric damage.
Complying with IS 2028:2004 guarantees reliable and durable wrenches suitable for industrial and professional use.
Why BIS Certification for Open Jaw Wrenches is Essential
Assures Safety and Reliability
Open Jaw Wrenches are exposed to high torque and mechanical stress. Substandard wrenches can bend, snap, or damage fasteners. BIS certification ensures IS 2028:2004 compliance, protecting both users and products.
Legal Compliance in India
Selling wrenches without BIS certification violates the BIS Act, 2016, risking fines, product seizure, or legal action. Certified wrenches ensure full compliance with Indian law.
Builds Customer Trust
The ISI mark signals consistent quality. Contractors, workshops, and industrial buyers prefer ISI-marked wrenches for safe, durable, and precise tools.
Market Advantage and Tender Eligibility
Government and industrial tenders mandate BIS-certified tools. Without certification, manufacturers lose eligibility for bids and export opportunities.
Standardized Quality Control
BIS-certified wrenches undergo rigorous testing for torque, hardness, deformation, and corrosion resistance, ensuring uniform quality across production batches.
Protects Brand Reputation
BIS certification demonstrates a brand’s commitment to safety and professionalism, reducing customer complaints and enhancing credibility in both domestic and international markets.
Supports Indian Standards and Exports
Compliance with IS 2028:2004 aligns with Make in India initiatives and enables manufacturers to compete in global industrial tool markets.
Understanding the ISI Mark for Open Jaw Wrenches
The ISI mark represents reliability, quality, and compliance. For Open Jaw Wrenches, it confirms adherence to IS 2028:2004, ensuring each wrench is tested for safety, torque, and durability.
Key Points About the ISI Mark:
- Conformity with IS 2028:2004: Confirms material, dimensional, and mechanical performance standards.
- BIS-Approved Testing: Wrenches are tested for torque resistance, hardness, jaw deformation, and corrosion.
- Rigorous Manufacturing Oversight: Each stage of production is inspected, from raw materials to finished products.
- Licensed Manufacturers Only: ISI mark can only be applied by holders of a valid BIS license.
- Consumer Confidence: Signals safe, durable, and reliable tools.
- Market Access: Enhances domestic and export market credibility.

Common Challenges in BIS Certification for Open Jaw Wrenches
The process for obtaining BIS certification for Open Jaw Wrenches (IS 2028:2004) can usually be simple with careful preparation, though several challenges repeatedly arise during the manufacturing process which may delay getting approval or complicate the process altogether. In knowing some pitfalls or challenges to avoid can prevent errors, save money, and increase the speed of compliance.
1. Incomplete Documentation
Missing or incorrect documents – such as factory layout, GST registration, or previously conducted QC reports – can lead to rejection or delay of the application for the license. BIS requests supporting documentation that outlines the legal registration, manufacturing procedures, and evidence of product conformity.
2.Failure to Meet IS 2028:2004
If the torque, hardness or jaw deformity tests fail, wrenches shall be considered to be non-conformance. Manufacturers may have to update their designs or retest products, resulting in extra costs and potentially prolonged timelines.
3. Factory Inspection Non-Conformance
BIS officers will inspect the manufacturing facility, manufacturer’s machinery, and quality control systems. If the manufacturer does not have a robust quality management system in place, lacks organized production flow, or lacks qualified technical staff this may lead to a failure of the inspection and rejection of the license.
4. Testing Delays
BIS-approved labs can experience high workloads or backlog, causing delays in testing torque, hardness, and corrosion resistance. Scheduling and timely sample submission are critical to avoid process bottlenecks.
5. Renewal Delays
BIS licenses are valid for 2 years. Failure to apply for renewal at least 3 months before expiry can lead to temporary suspension or cancellation, affecting the legality of selling ISI-marked wrenches.
6. Consultant Errors
Less experienced consultants may give you an incomplete or improperly prepared document, leading to rework and unnecessary costs. Using a provider with expertise like Diligence Certification will help reduce that risk.
7. Costs of Doing Testing
Small or medium-sized manufacturers may struggle to pay for testing, inspection, and licensure costs, especially if the certifier requires separate compliance for each wrench size. All manufacturers, particularly startups or new entrants into the market, must plan a budget for testing so testing will go smoothly.
8. Not Understanding IS 2028:2004
The absence of technical know-how on material grades, torque limits, or mechanical performance can result in design errors that are not compliant to inspection or testing. Likewise, manufacturers may fall behind on BIS standards and revisions.
Cost of BIS Certification
