浙江高强度紧固件有限公司
Manufacturer publishing high-strength fasteners, high-temperature preload disc springs and related spring products under the 高强 brand. This profile uses the hexagon-bolt catalogue selectively. Conflicting nut and stud tables are recorded as unresolved source issues, so their dimensions are not reproduced.
Select a family to see the source, dimensional range and questions to confirm. Images below identify product families. Read each caption for the source and illustration status.
Images are credited individually. Technical illustrations explain published dimensions; they are not factory photographs. Series photographs do not establish individual specifications.
| Published reference | Family diameter envelope | Published class labels |
|---|---|---|
| DIN 931 / 933 | M6–M100 | 6.8 / 10.9 |
| ISO4014 / 4017 | M6–M100 | 6.8 / 10.9 / 12.9 |
These unusually broad manufacturer-published envelopes are not the dimensional scope of the referenced standards. No edition is shown. Confirm current drawing, actual size/class combination, thread length and any oversize or nonstandard agreement before ordering. No equivalence between DIN and ISO is asserted.
Original comparison source ↗Selected DIN 931/933 and ISO4014/4017-labelled rows are compared below. They are the manufacturer’s broad family envelopes, not confirmation of every size, class, length or current standard combination.
Company publication ↗Both families are listed, but repeated bolt tables appear under their product headings. Request separate controlled nut and stud catalogues before assigning parameters.
Company publication ↗The company introduction and product navigation list related spring and rod families. Their specific dimensions, materials and operating conditions require separate source review.
Company publication ↗The following identity information is attributed to the company website. It does not replace registration or supplier approval checks.

The company describes design, manufacture and testing of high-strength fasteners and spring products. The producing site and operations for the chosen order must be established.
The equipment page displays premises and equipment. No machine inventory, capacity, calibrated measurement scope or lot test result is independently established here.
The profile lists management-system and laboratory claims. Current certificate numbers, expiry dates, product scope and laboratory accreditation schedule were not verified.
These are public-document leads. Current certificate validity and product applicability have not been independently established.
The hex-bolt page contains broad standard-labelled family ranges.
Request full standard and edition, dimensions, thread length, class, material, heat treatment and finish for the exact order.
Nut and stud detail tables repeat bolt entries.
Obtain corrected family-specific data directly from the manufacturer; do not use bolt standards as nut or stud specifications.
Company publications describe testing and quality resources.
Request current site-specific certificates, calibration/accreditation scope, material traceability and agreed dimensional/mechanical reports.
Buyer guidance from Honyawn Atlas — not a statement of the manufacturer’s commercial terms.
State bolt/nut/stud form, standard and edition, thread diameter/pitch, length and drawing revision.
Specify steel/material grade, property class, heat treatment, coating and any service-temperature or corrosion requirement.
Agree sampling, dimensions, mechanical tests, traceability and any application-specific documents.
Confirm legal seller, plant, quantities, MOQ, price, lead time and delivery terms.
Include the drawing or standard, quantity per size and delivery destination. Select quotation, samples or technical documents in the request form.
