Snap-on TQSS050A Torque Driver, Stubby Torqometer U.S. Basic Dial, 6 in-lb / 96 in-oz, 5-1/4″ Long

Description

Wiring harness and avionics box builders often meet the same problem: the screw sits deep, the cable bundle sits in front, and a long driver will not line up. The Snap-on TQSS050A torque driver answers with a body just 5-1/4 inches long. Its U.S. basic dial reads to 6 in-lb, or 96 in-oz, so the assembler sees light torque build in real time.

Short reach, light load: where the TQSS050A works

Aerospace and defense suppliers in Vietnam build to drawings that quote torque in inch units. Many of those values sit in the low pound-inch band, where a hand guess is risky. For example, these jobs suit a stubby 6 in-lb dial:

• Jackscrews and jackposts on rectangular connectors behind a harness.
• Cover and access plate screws, as well as lid screws, on small avionics enclosures.
• Board standoff screws, such as those deep inside a crowded chassis.
• Clamp screws on cable ties, P-clips and grounding lugs in test racks.

However, always take the final value from the drawing or the connector maker, rather than a general chart.

TQSS050A data in brief

• Body: stubby, 5-1/4 in long.
• Dial: U.S. reading, basic model with one needle.
• Range: 96 in-oz / 6 in-lb, roughly 0.68 N·m.
• Steps: 2 in-oz / 1/8 in-lb.
• Case: PB47 storage case.

Snap-on rates Torqometer drivers at 2% of reading from 20% of full scale upward. So plan for targets between about 1.2 and 6 in-lb on this model.

Working with a single needle

The basic dial on the Snap-on TQSS050A torque driver returns to zero once you relax your grip. Therefore the reading has to happen during the turn. First, hold the tool square to the screw, keep your eyes on the scale, and ease off as the needle nears the mark. Also, in a dim bay, a small torch on the dial face helps a lot.

TQSS050A or one of its siblings?

The same 6 in-lb row has a full-length TQS050A at 7-3/4 inches, which gives a larger grip when access allows. Also, the TQSS050FUA keeps the stubby body but adds a peak pointer for inspectors. If your values drift past 6 in-lb, the 12 in-lb TQSS1A is the next stubby size.

Harness shop questions about the TQSS050A

Does the Snap-on TQSS050A torque driver read in newton-meters?

No, because it is a U.S. reading tool in in-oz and in-lb. So for metric drawings, convert first; 6 in-lb is about 0.68 N·m.

How does the stubby length change the feel?

A short handle means less leverage, so you apply the load more gently. That suits the light values in this range.

Where do we store it between jobs?

Snap-on supplies the PB47 storage case, which keeps the dial lens safe in a tool crib.
